Alexander Mattison Injury News & Updates

Dolphins coach Mike McDaniel said Tuesday that Mattison (neck), who was placed on season-ending IR on Monday, does not have a career-ending injury, David Furones of the South Florida Sun Sentinel reports.

Mattison suffered a neck injury during Sunday's preseason tie against the Bears that required surgery, and will cause him to miss the entire 2025 season. It's encouraging that Mattison may be back in action for the 2026 campaign, though given that he inked only a one-year deal with Miami this offseason, it's likely that his next opportunity will come with another organization. With Mattison on IR, both second-year pro Jaylen Wright and rookie sixth-rounder Ollie Gordon benefit from a clearer path to touches behind starter De'Von Achane.

The Dolphins placed Mattison (neck) on injured reserve Monday

Mattison emerged from Sunday's preseason tie with the Bears with neck soreness and then reportedly underwent neck surgery not longer afterward, per Adam Schefter of ESPN. With Mattison's move to IR, the severity of the injury more or less has been confirmed, and he'll miss the 2025 season, barring getting cut with an injury settlement. Both Jaylen Wright and rookie Ollie Gordon now both have clearer paths to locked-in reserve roles behind Miami's top RB De'Von Achane.

Mattison reportedly underwent season-ending neck surgery Sunday, Adam Schefter of ESPN reports.

We'll await further confirmation from the Dolphins, but it looks like Mattison, who hurt his neck during Sunday's game against the Bears, is a candidate for IR. In his looming absence, look for the team to add depth to a backfield that also includes De'Von Achane, Jaylen Wright and Ollie Gordon.

Dolphins head coach Mike McDaniel said Sunday that Mattison (neck/shoulder) is "doing well" after being forced out of Miami's preseason game against the Bears due to "neck and shoulder soreness," David Furones of the South Florida Sun Sentinel reports.

McDaniel confirmed that Mattison isn't currently in the concussion protocol, per Furones. The veteran running back looked capable before leaving the field Saturday, recording three carries for eight yards and a score plus one catch for 21 yards on two targets.

Mattison went to the locker room during Sunday's preseason game against the Bears due to an apparent head injury, Alain Poupart of SI.com reports.

Mattison was tackled and thrown to the ground head-first early in the fourth quarter, which prompted trainers to check in on the veteran running back. He was able to walk off the field and into the locker room under his own power, but he's unlikely to return to Sunday's exhibition game, which opens the door for Ollie Gordon to lead the backfield down the stretch. If Mattison doesn't return, he'll finish with three carries for eight yards and a touchdown along with one catch (on two targets) for 21 yards.

Mattison is signing with the Dolphins, Jordan Schultz of Fox Sports reports.

Mattison is swapping teams with Raheem Mostert, whose deal with the Raiders was reported about two hours earlier. While Mostert perhaps has a chance to rebound from a disappointing 2024 and earn a key role, Mattison will merely be competing for a backup job behind De'Von Achane. The Dolphins presumably hope 2024 fourth-round pick Jaylen Wright secures the second spot on the depth chart, with Mattison essentially being a backup plan for the backup. It's a tough situation for earning playing time, albeit with the outside chance of a handsome payoff if injuries eventually thrust him into a starting role in Mike McDaniel's offense.

Mattison rushed the ball six times for 20 yards in Sunday's 34-20 loss to the Chargers. He added four receptions on five targets for 11 yards.

Mattison served as the clear lead back for Las Vegas with Ameer Abdullah (foot) sidelined, though he had only one rushing attempt after halftime despite the Raiders being down one score until late in the contest. The story of this game also encapsulated Mattison's campaign, as he averaged a miserable 3.2 yards per carry in one of the least explosive offenses in the league. He'll hit free agency this offseason and will likely sign a short-term deal with the hopes of serving as a change-of-pace back.

With Ameer Abdullah (foot) ruled out for Sunday's season finale against the Chargers, Mattison is in line to start at running back for the Raiders in Week 18, per Tashan Reed of The Athletic.

Mattison, who carried 10 times for 32 yards and caught one of three targets for six yards in last weekend's win over the Saints (a game in which Abdullah logged 20 carries for 115 yards to go along with three catches), is thus in line for an expanded role Sunday, with Chris Collier and Dylan Laube to a lesser degree available to mix in, per Vic Tafur of The Athletic. With that in mind, Mattison offers fantasy managers who are dealing with injuries or resting starters with a Week 18 pivot option.

Mattison is expected to be the Raiders' starting running back Sunday versus the Chargers with Ameer Abdullah (foot) listed as doubtful for that contest, Tashan Reed of The Athletic reports.

Among his 13 appearances this season, Mattison has surpassed 4.0 YPC just one time (5-60-0 back in Week 4 against the Browns), and overall he's averaged 3.2 yards on his 126 rushes to date. He at least has supplemented poor performance on the ground with 32 catches (on 43 targets) for 283 yards while also scoring five total TDs. With Abdullah likely sidelined this weekend, Mattison should take on an expanded role, but he also may yield RB reps to Chris Collier and maybe even Dylan Laube.

Mattison rushed 10 times for 32 yards and caught one of three targets for six yards in Sunday's 25-10 win over the Saints.

Mattison somewhat surprisingly ceded the start at running back to 31-year-old Ameer Abdullah, who proved entirely more effective with 20 carries for 115 yards to go along with three receptions for 32 yards, while Mattison averaged just 3.45 yards per touch. Abdullah likely earned himself first dibs at a larger share of the backfield workload again in Week 18 versus the Chargers, as Mattison's efficiency concerns remain.

Mattison rushed the ball 12 times for 27 yards and a touchdown in Sunday's 19-14 win over the Jaguars. He added four receptions on seven targets for 29 yards.

Mattison led the Las Vegas backfield in the absence of Sincere McCormick (ankle), totaling 16 touches as compared to 12 for Ameer Abdullah. While he has been involved as a pass catcher throughout the season, it was particularly positive to see his involvement as a receiver remain intact despite the recent emergence of Abdullah. On the other hand, Mattison was ineffective on the ground, with the exception being a one-yard touchdown run early in the second quarter. This backfield is very likely to remain split for the rest of the season, but Mattison should see plenty of touches in Week 17 against the Saints.

Mattison took over for injured starter Sincere McCormick (ankle) in the second half of Monday's loss to the Falcons, finishing with 24 rushing yards (one fumble lost) on seven carries while corralling two of four targets for three receiving yards.

Mattison returned from an ankle injury of his own Monday before being thrust into a prominent role once Las Vegas' starting running back was ruled out at halftime. The veteran tailback played poorly on his nine touches, losing a fumble and getting tackled for a safety. Fellow backup Ameer Abdullah produced 66 yards and a score on 10 combined touches (primarily as a receiving option) for comparison. If McCormick is forced to miss time, Mattison figures to be the next man up given his experience and success as a starter in the past, with Abdullah likely being mixed in sporadically against the Jaguars on Sunday.

Mattison (ankle) was a full participant in practice Thursday, Paul Gutierrez of ESPN.com reports.

Mattison's full participation in practice to kick off Week 15 prep clears the way for him to put an end to his three-game absence Monday against the Falcons, but he'll likely find himself in a smaller role than he enjoyed prior to missing time with the ankle injury. Per Levi Edwards of the Raiders' official site, head coach Antonio Pierce announced Wednesday that Sincere McCormick will remain the team's starting running back moving forward, which likely means Mattison will see a reduction in the 9.7 carries per game he had averaged for the season before suffering the injury. McCormick hasn't shown much prowess as a receiver, however, so Mattison could be called upon to replace him on passing downs after averaging a healthy 9.8 yards per reception prior to his recent absence.

Head coach Antonio Pierce relayed Wednesday that Mattison (ankle) will probably be active Monday night against the Falcons, Paul Gutierrez of ESPN.com reports.

While Mattison -- who last played in Week 11-- is trending toward a return to action Monday, Pierce noted that Sincere McCormick -- who has run well of late -- would remain the Raiders' top back nonetheless. Mattison is thus poised to rejoin the team's backfield mix in a complementary role behind McCormick, with Ameer Abdullah also on hand. In that role, Mattison's Week 15 fantasy upside appears modest.

Mattison (ankle) is inactive for Sunday's game against the Buccaneers.

With Mattison and Zamir White (quadricep) set to miss their third consecutive games, the Raiders will turn to Ameer Abdullah and Sincere McCormick to pick up most of the snaps out of the backfield. Prior to missing time with the ankle injury, Mattison had been serving as the Raiders' lead back and had earned at least eight touches in each of his last six appearances, but it's unclear if he'll be in store for meaningful volume once he shakes off the ankle injury. Mattison is on an expiring contract, and after averaging just 3.3 yards per carry on the season, the non-contending Raiders may not be incentivized to give extensive work to a player who might not be part of the team heading into 2025.

Mattison (ankle), who is questionable for Sunday's Week 14 battle against the Buccaneers, isn't likely to play, Adam Schefter of ESPN reports.

Mattison was able to log a trio of limited practices this week, but it doesn't appear that he's ready to return to game action. If he is indeed held out Sunday, it will be the veteran tailback's third straight absence. Zamir White (quadriceps) has already been ruled out for Week 14, so Las Vegas' backfield will likely consist of Ameer Abdullah, Sincere McCormick and Dylan Laube against Tampa Bay.

Mattison (ankle) is listed as questionable for Sunday's game in Tampa Bay, Paul Gutierrez of ESPN.com reports.

For a second straight week, Mattison has operated with a cap on his reps and ended it as questionable to suit up. He ultimately was inactive last Friday at Kansas City, but if he's able to return to action this weekend, there's a chance he'd retake the the Raiders backfield from Ameer Abdullah and Sincere McCormick with Zamir White (quadriceps) still sidelined.

Mattison (ankle) was a limited participant in Thursday's practice, Tashan Reed of The Athletic reports.

Mattison has now been listed as limited on five consecutive practice reports, but after missing the Raiders' last two contests, he may need to upgrade to full participation Friday in order to avoid carrying a designation into Sunday's game against the Buccaneers. Even if Mattison gets the green light to play Sunday, he may not take on as expansive of a role out of the Las Vegas backfield as he had enjoyed prior to sustaining the ankle injury. Mattison is averaging just 3.3 yards per carry on the season, and the Raiders had success on the ground in his absence with 2022 undrafted free agent Sincere McCormick, who gained 97 yards on 17 totes (5.7 YPC) over the past two weeks.

Mattison (ankle) was a limited practice participant Wednesday, Paul Gutierrez of ESPN.com reports.

Fellow running back Zamir White (quadriceps) was a non-participant and thus appears more likely than Mattison to miss a third straight game. Ameer Abdullah filled in as the starter the past two weeks, but Sincere McCormick had a significant role in the second game, taking 38 percent of snaps and a team-high 12 carries (for 64 yards) in the 19-17 loss to Kansas City on Friday. It's hard to say what Mattison's role will be if he returns this Sunday against Tampa Bay, considering he's averaging 3.3 yards per carry this season and has reached 40 rushing yards in just one of his five starts.

Mattison (ankle) is inactive for Friday's game against the Chiefs.

With Mattison and Zamir White (quadriceps) both inactive, Ameer Abdullah is in a position to continue to lead the Raiders' backfield Friday, with practice squad elevation Sincere McCormick mixing in, while Dylan Laube is on hand in reserve. The next chance for either Mattison or White to return to the lineup arrives Dec. 8 versus the Buccaneers.

Mattison (ankle) is listed as questionable for Friday's game against the Chiefs.

While Mattison, who the Raiders deemed limited on their Tuesday through Thursday practice reports, has a chance to face Kansas City, Zamir White (quadriceps) was ruled out by the team. Confirmation of Mattison's Week 13 status will arrive once Las Vegas' inactives are posted ahead of Friday's 3:00 p.m. ET kickoff, but if he's limited or out, Ameer Abdullah would be in line to continue to see added backfield snaps, with Sincere McCormick and Dylan Laube also available to mix in.

Mattison (ankle) was a limited practice participant Wednesday, Paul Gutierrez of ESPN.com reports.

Mattison at least is ahead of fellow Raiders running back Zamir White, who hasn't practiced since suffering a quad injury Week 11. Mattison injured his ankle later in the same game and then missed Week 12, allowing Ameer Abdullah to play 88 percent of snaps in a loss to Denver this past Sunday. Mattison could be back in the lead role if he's active for Friday's game against the Chiefs at 3:00 p.m. ET.

Mattison (ankle) was estimated as a limited participant in Tuesday's practice walkthrough, Tashan Reed of The Athletic reports.

Though the Raiders held a walkthrough Tuesday, that Mattison was deemed limited is an improvement over his trio of DNPs last week. The running back was unable to play against Denver on Sunday, as was No. 2 back Zamir White (quadricep), leaving ball-carrying duties primarily to Ameer Abdullah. White was estimated as not practicing Tuesday, and if neither he nor Mattison can return Friday against Kansas City, Abdullah figures to lead Las Vegas' rushing attack again.

Mattison (ankle) is inactive for Sunday's game against the Broncos.

With Zamir White (quadricep) also inactive, Ameer Abdullah is next up at running back for the Raiders on Sunday, while Dylan Laube and practice-squad elevation Sincere McCormick are also in line to mix in versus Denver. The next chance for Mattison and/or White see game action will arrive this coming Friday at 3:00 p.m. ET, when the Raiders face the Chiefs on the road.

Mattison (ankle) will be listed as doubtful for Sunday's game against the Broncos, Tashan Reed of The Athletic reports.

Meanwhile, Zamir White (quadricep) will also be deemed doubtful for the contest, paving the way for the Raiders to likely be without both backs this weekend. If the duo is inactive versus Denver, Las Vegas would likely start Ameer Abdullah at running back, with Dylan Laube and Sincere McCormick also in the mix, per Vic Tafur of The Athletic.

Mattison (ankle) remained sidelined at practice Thursday.

The same applies to Zamir White (quadricep), with both backs in danger of missing Sunday's game against the Broncos. Friday's final injury report will reveal the game status of the duo, but if neither are available this weekend, Ameer Abdullah and Dylan Laube would be in line for expanded roles in Week 12, with Sincere McCormick and/or Chris Collier representing potential practice squad elevations.

Mattison (ankle) won't practice Wednesday, Paul Gutierrez of ESPN.com reports.

The same applies to Zamir White (quad), with both players having been forced out of this past Sunday's loss to the Dolphins. The duo's status is thus worth monitoring in advance of this weekend's game against the Broncos, but for the time being the healthiest running backs on the Raiders' active roster are Ameer Abdullah and Dylan Laube, with Chris Collier and Sincere McCormick candidates to be elevated from the practice squad ahead of Week 12 action.

Mattison left Sunday's game against the Dolphins with an ankle injury.

Meanwhile, fellow RB Zamir White (quad) was also forced out of the contest, leaving Ameer Abdullah to handle the team's backfield duties. Before his injury, Mattison carried five times for 19 yards and caught all three of his targets for 50 yards.

Mattison rushed nine times for 36 yards in the Raiders' 41-24 loss to the Bengals on Sunday.

Mattison once again led the Raiders' backfield in carries, outpacing Zamir White, who did score a rushing touchdown, by three attempts overall. Neither back was targeted in the passing game, and the non-fantasy-friendly pecking order is likely to persist through a Week 10 bye and into a Week 11 road matchup against the Dolphins on Sunday, Nov. 17.

Coach Antonio Pierce said Wednesday that Mattison will remain the starting RB, but Pierce also wants to get Zamir White more involved, Levi Edwards of the Raiders' official site reports.

Mattison started the last four games and took at least 57 percent of snaps and 17 touches in each contest, averaging 16.5 carries for 44.5 yards (2.7 YPC) and 3.8 catches for 28.8 yards (7.2 YPT) while scoring one touchdown. The volume has made him a reasonable fantasy starter, at least in PPR leagues, but his struggles on the ground seemingly open the door for White to take on a significant role again -- and possibly as soon as this Sunday at Cincinnati.

Mattison rushed the ball 14 times for 15 yards in Sunday's 27-20 loss to the Chiefs. He added five receptions on five targets for 29 yards.

Mattison was the only Raider to record more than two carries, but he didn't do anything to earn the continued opportunity. His longest rush went for just five yards, and four of his 14 carries went for zero or negative yards. Mattison did manage to salvage his day as a receiver, as he tied for second on the team with five targets. Zamir White saw only two carries and totaled -1 yards, though it wouldn't be surprising to see the Raiders mix up their running back usage in Week 9 against the Bengals.

Mattison rushed 23 times for 92 yards and caught all three of his targets for 31 yards in Sunday's 20-15 loss to the Rams.

The Raiders got Zamir White (groin) back for the first time since Week 4, but Mattison got 23 carries to White's three. Having usurped White as the top option in Vegas' backfield, Mattison should have a high touch floor moving forward on a Raiders team that wants to play smash mouth football due to the team's lack of talent in the passing game. Mattison has logged at least 17 touches in three consecutive games heading into a Week 8 home game against the Chiefs.

Mattison rushed the ball 14 times for 33 yards and a touchdown in Sunday's 32-13 loss to the Steelers. He added five receptions on five targets for 32 yards.

Mattison served as the lead back for the second consecutive week in the absence of Zamir White (groin). He accounted for the majority of his production on the Raiders' first offensive possession, during which Mattison recorded 25 yards on the ground and 19 on the ground while also recording his touchdown. If White is sidelined again for a Week 7 matchup against the Rams, Mattison should have the ongoing chance to be productive thanks to projected volume.

Mattison is in line to lead the Raiders backfield Sunday against the Steelers with Zamir White (groin) inactive.

With White on the pine Week 5 at Denver, Mattison started and earned a 57 percent snap share en route to 15 carries for 38 yards and two catches (on three targets) for 23 yards. Meanwhile, Ameer Abdullah handled 44 percent of plays, with most of his 51 yards from scrimmage coming on a 40-yard carry, though he did have a three-yard touchdown run. A similar breakdown of reps between Mattison and Abdullah likely will come to pass Sunday.

Mattison rushed the ball 15 times for 38 yards in Sunday's 34-18 loss to the Broncos. He added two receptions on three targets for 23 yards.

Mattison took over as the lead back in the Raiders' backfield and tripled his previous high in carries for the season. He was ineffective with the opportunity, however, as his longest rush went for just eight yards while averaging 2.5 yards per carry. Mattison salvaged his day to some degree with his work as a pass catcher, though it wouldn't be a surprise to see Ameer Abdullah mix in more in Week 6 against Pittsburgh if Zamir White (groin) remains sidelined.

Mattison is set to operate as Vegas' top running back against the Broncos on Sunday, as Zamir White (groin) has been ruled out, Paul Gutierrez of ESPN.com reports.

White picked up the groin injury in practice Wednesday and subsequently sat out Thursday and Friday. Even before the injury to White, Mattison had been headed for an uptick in opportunities, as Mattison's averaging 5.1 yards per carry on 17 attempts this season compared to White's paltry 3.1 YPC on 49 carries. Ameer Abdullah and Dylan Laube could also see more touches in White's absence.

Raiders head coach Antonio Pierce said Monday that Mattison's recent quality of play has earned him more work and that he's "going to get it," Adam Hill of the Las Vegas Review-Journal reports.

Mattison only handled five carries during Las Vegas' 20-16 win over the Browns in Week 4, but he compiled 60 yards on the ground. Meanwhile, starter Zamir White rushed 17 times for 50 yards and lost a fumble, which was recovered by Cleveland's defense and returned for a score in the fourth quarter. Through the first four games of the regular season, Mattison is averaging 5.1 yards per carry and has scored a total of three times, while White is averaging just 3.1 yards per carry and has yet to score. It won't be surprising if Mattison forces a more even split of touches on the road against Denver on Sunday.

Mattison rushed three times for seven yards and a touchdown in Sunday's 36-22 loss to the Panthers. He also caught all three of his targets for 37 yards.

The Raiders' efficiency issues on the ground continued Sunday, but Mattison vultured fellow running back Zamir White near the goal line for a second straight week by putting the team on the board with a two-yard rushing touchdown late in the first quarter. Additionally, Mattison remained the primary receiving option out of the backfield ahead of Ameer Abdullah, who was targeted twice. Looking ahead to Week 4, Las Vegas plays host to a Browns defense that just ceded six collective receptions for 60 yards to Giants running backs Devin Singletary and Tyrone Tracy.

Mattison rushed four times for one yard and a touchdown in Sunday's 26-23 win over the Ravens.

Mattison wasn't targeted in the passing game Sunday after quarterback Gardner Minshew looked his way on six separate occasions in the season opener, but Mattison was dealt a goal-line carry late in the third quarter, which he converted for a one-yard touchdown run. Aside from falling into the end zone, Mattison was limited to just 0.25 yards per carry as the Raiders' entire backfield was stymied on the ground by the Ravens' defensive front throughout the contest. Both Mattison and Zamir White will look to find more space to run against a struggling Panthers team at home Week 3.

Mattison rushed five times for 19 yards and caught four of six targets for 43 yards and a touchdown in Sunday's 22-10 loss to the Chargers.

Mattison not only scored the Raiders' only touchdown of the contest on a 31-yard reception in the first quarter, but he also out-snapped starting running back Zamir White by a count of 36 to 23. Opening as big underdogs against the Ravens in Week 2, Mattison once again could see a healthy share of the backfield split if a similar second-half script requires the 26-year-old to be involved on more passing downs than the aforementioned White, who figures to handle the bulk of the early-down rushing work after taking 13 carries for 44 yards in Sunday's loss at SoFi Stadium.

Mattison rushed five times for 15 yards and secured one of two targets for six yards in the Raiders' 27-12 preseason loss to the Cowboys on Saturday night. He also returned one kickoff for 23 yards.

Mattison worked as the second running back in behind Zamir White, a hierarchy that's expected to be mirrored during the regular season. Mattison shouldn't need any additional reps to get ready for the regular season and will be a valuable complementary presence, so he's likely to sit out of the Raiders' preseason finale against the 49ers on Friday night.

As the coming season approaches, Mattison profiles as Zamir White's top backup at the running back position, Tashan Reed of The Athletic reports.

Following the free-agent departure of Josh Jacobs, White heads into the coming season as the team's presumed lead back, while Mattison is line to work behind him in a complementary role that would set the former Minnesota Viking up to be next up for added carries should White suffer an injury. Meanwhile, as the Raiders' second preseason game approaches, Reed indicates that Ameer Abdullah and rookie Dylan Laube are still competing to see who secures Las Vegas' primary third-down RB duties.

Mattison is in line to sign with the Raiders, Tom Pelissero of NFL Network reports.

In 16 games for the Vikings during the 2023 regular season, Mattison had 180 carries for 700 yards and caught 30 of his 44 targets for 192 yards and three receiving TDs. With the Raiders, Mattison -- who turns 26 in June -- is slated to provide the team with needed backfield depth and a complementary option alongside 2022 fourth-rounder Zamir White following the free-agent departure of Josh Jacobs. Assuming White serves as Las Vegas' top RB option, Mattison's weekly upside will be modest, but if White is injured or struggles at all as the 2024 season progresses, Mattison could reenter the fantasy lineup equation.

The Vikings officially released Mattison on Monday.

Mattison was initially informed of his release by the team late February, and he's now officially a free agent after having signed a two-year, $7 million deal with the team last offseason. The veteran back is coming off a solid season from a volume perspective, with 700 yards on a career-high 180 carries across 16 games, but those stats are marred by a lack of explosiveness (3.9 YPC) and turnovers, with three total fumbles, two of which were lost. Mattison has now turned in three straight seasons averaging less than 4.0 YPC. Minnesota, in the meantime, should be in the market for backfield options to join Ty Chandler.

The Vikings informed Mattison they will be releasing him Thursday, Adam Schefter of ESPN reports.

Mattison took over as the primary running back in Minnesota after Dalvin Cook was released last offseason. He had a good season from a volume perspective, logging a career-best 180 carries while also racking up 30 receptions. However, he lacked explosiveness, evident from the fact that he had just one rush over 20 yards. He'll likely be looking for a short-term deal as a complementary rusher this offseason.

Mattison rushed seven times for 24 yards and caught his lone target for five yards in Sunday's 30-20 loss to the Lions.

Mattison continued to operate as the backup running back behind Ty Chandler, concluding a disappointing season for the veteran. In 16 games, the 25-year-old totaled rushed 180 times for 700 yards, failing to find the end zone on the ground. Mattison did, however, find the end zone three times through the air while catching 30 passes for 192 yards. A popular value pick at running back ahead of the 2023 campaign, Mattison's future as a starter in Minnesota seems to be up in the air at best. With that said, he'll enter the final year of his contract with the Vikings next season before becoming an unrestricted free agent in 2025.

Mattison had three carries for 17 yards and two receptions for 13 yards on two targets in Sunday's loss to Green Bay.

Mattison again took a back seat to starter Ty Chandler as he played on 21 of the offense's 53 snaps. Chandler played on 30 snaps. Mattison looks set to work behind Chandler again for the regular season finale next week at Detroit.

Mattison (ankle) doesn't have an injury designation for Sunday night's game against Green Bay.

His status was never really in doubt after he returned from the ankle injury last week and took two touches on five snaps in a 30-24 loss to the Lions. Mattison upgraded to full practice participation Friday after limited sessions earlier in the week, and there's a good chance he gets at least a little more playing time Week 17 given that he's healthier and Ty Chandler managed just 17 total yards last week. Chandler still looks like the better fantasy play out of the two, having taken 65 percent of the snaps last week after rumbling for 157 total yards in a loss to Cincinnati the week prior.

Mattison (ankle) practiced on a limited basis Thursday.

Since sitting out Week 15 due to a sprained right ankle, Mattison handled a bit role in the offense (two carries on five offensive snaps) this past Sunday versus the Lions and now has been listed as limited on back-to-back injury reports during Week 17 prep. He likely will need to return to all activity Friday in order to avoid a designation ahead of Sunday's game against the Packers. Even if he's able to suit up again this weekend, though, Mattison may play second fiddle to RB Ty Chandler, who logged 65 percent of snaps and had eight rushes for 17 yards and a touchdown against Detroit.

Mattison (ankle) was listed as limited on Wednesday's estimated practice report.

Mattison sat out Week 15 due to a low right-ankle sprain, but he was able to return to action this past Sunday against the Lions, when he turned two carries into minus-1 yard on five offensive snaps. Fellow running back Ty Chandler paced the Vikings backfield with 36 snaps on offense, but he managed just eight carries for 17 yards and one touchdown. As long as Mattison's health is compromised, he may continue to play second fiddle to Chandler down the stretch, assuming the former is active on game days. In the end, Friday's injury report will reveal whether or not Mattison enters the weekend with a designation for Sunday's NFC North matchup with the Packers.

Mattison had two carries for minus-1 yard during Sunday's 30-24 defeat to the Lions.

In a game in which the Vikings were in catch-up mode from the outset, the offense led by quarterback Nick Mullens leaned toward the air and not the ground, resulting in 36 pass attempts and just 11 rushes. Fellow running back Ty Chandler handled eight of those carries, and the only member of the backfield to receive a target was FB C.J. Ham, despite WR Jordan Addison (ankle) and TE T.J. Hockenson (knee) leaving the contest with injuries. According to Kevin Seifert of ESPN.com, there was an expectation that Mattison would be the second RB behind Chandler in the former's return from a one-game absence due to a sprained right ankle, and Mattison's upcoming activity level during Week 17 prep may give a sense of how much work he'll be able to handle Sunday, Dec. 31 against the Packers.

Mattison (ankle) is active for Sunday's game against the Lions.

Coming off his first absence of the season in the Vikings' Week 15 overtime loss to the Bengals, Mattison turned in just one limited practice this week, but the coaching and training staffs apparently came away encouraged enough with his health to give him the green light to play Saturday. However, Mattison likely isn't close to 100 percent healthy and could be in store for a smaller role than usual out of the backfield, as Ty Chandler is expected to serve as the team's lead back, according to Kevin Seifert of ESPN.com. Head coach Kevin O'Connell hasn't outlined his plans for the backfield beyond Week 16, though he suggested earlier in the week that Chandler could have an opportunity to stake his claim to the No. 1 role beyond Sunday's game. Chandler broke out for the best performance by a Minnesota running back all season in last week's loss to Cincinnati, finishing with 132 yards and a touchdown on 23 carries to go with three catches for 25 yards on four targets. Mattison, meanwhile, is averaging a middling

Mattison (ankle), who is listed as questionable for Sunday's game against the Lions, is expected to play, but he may be less than 100 percent healthy, Tom Pelissero of NFL Network reports.

After sitting out the Vikings' 27-24 overtime loss to the Bengals in Week 15 due to a sprained right ankle, Mattison has put himself in position to play Sunday after he was able to return to practice Friday as a limited participant. When active this season, Mattison has typically paced the Vikings in snaps and touches out of the backfield, but Pelissero suggests that the 25-year-old will likely find himself in a supporting role Sunday while Ty Chandler gets another chance to lead the backfield after producing 157 yards from scrimmage and a touchdown on 26 touches in Week 15. Head coach Kevin O'Connell intimated earlier in the week that Chandler had likely earned himself another opportunity as the lead back, and O'Connell even seemed to leave the door open for Chandler sticking atop the depth chart once Mattison is closer to 100 percent healthy. How both Chandler and Mattison perform Sunday could have significant sway in how the running-back depth chart shakes out for Weeks 17 and 18.

Mattison (ankle) is listed as questionable for Sunday's game against the Lions.

After missing the Vikings' 27-24 overtime loss to the Bengals last weekend and then sitting out the team's first two practices of Week 16, Mattison returned to practice Friday. The running back appears to have demonstrated enough progress in his recovery from a right knee sprain to at least put himself in consideration to play Sunday, but final word on his status won't arrive until Minnesota releases its inactive list 90 minutes prior to the game's 1 p.m. ET kickoff. Even if Mattison gets clearance to play, he'll likely be filling a supporting role behind Ty Chandler, who broke out for 23 carries for 132 yards and a touchdown to go with three catches for 25 yards while serving as Minnesota's lead back last week. According to Kevin Seifert of ESPN.com, head coach Kevin O'Connell hinted earlier this week that Chandler could remain in a featured role moving forward on the heels of his big game, especially after Mattison had lost two fumbles and was limited to 3.9 yards per carry and no touchdowns on 168 totes th

Mattison (ankle) returned to practice Friday, Ben Goessling of the Minneapolis Star Tribune reports.

It's his first participation of any kind since spraining an ankle during a 3-0 win over the Raiders in Week 14. Ty Chandler then took 81 percent of Minnesota's snaps on offense en route to 157 total yards in an overtime loss to the Bengals in Week 15, so he may remain the lead back even if Mattison is active for Sunday's game against Detroit.

Mattison (ankle) didn't practice Thursday.

Mattison looks to be trending toward missing a second straight game this weekend against the Lions, as he hasn't been able to practice in any capacity since sustaining a right ankle sprain in the Vikings' 3-0 win over the Raiders in Week 14. Ty Chandler looks poised to serve as Minnesota's lead back Sunday, and head coach Kevin O'Connell alluded Wednesday to the possibility of the second-year player remaining atop the depth chart even Mattison has fully moved past the ankle injury. Mattison has mustered just 3.9 yards per carry and zero touchdowns on the ground in addition to losing two fumbles over his 13 appearances in 2023, while Chandler came through with the best performance by any Vikings running back in this past Saturday's 27-24 overtime loss to the Bengals. Chandler carried 23 times for 132 yards and a touchdown and added three catches for 25 yards on four targets in the loss, and the Vikings could look to reward him for his efforts.

Mattison (ankle) was held out of practice Wednesday.

Mattison hasn't practiced since spraining his right ankle in the middle of the Vikings' 3-0 win in Las Vegas in Week 14, which sidelined him this past Saturday at Cincinnati. Coach Kevin O'Connell told Kevin Seifert of ESPN.com on Wednesday that he hasn't ruled Mattison out for Sunday's game versus the Lions, but Minnesota likely will lean more on Ty Chandler at running back, even if the former is available. Mattison's listing on the team's last two Week 16 injury reports could reveal whether he has a chance to play this weekend.

Mattison (ankle) wasn't spotted during the part of Wednesday's walkthrough open to the media, Kevin Seifert of ESPN.com reports.

Mattison sprained his right ankle during the Vikings' Week 14 win at Las Vegas, and while the severity of the injury hasn't been revealed, he hasn't been able to practice in the interim and missed this past Saturday's overtime loss in Cincinnati. On Wednesday, coach Kevin O'Connell relayed to Seifert that he wouldn't rule out Mattison for Sunday's game against the Lions but also implied Ty Chandler likely will be Minnesota's main running back in that contest. Mattison's activity level to begin Week 16 prep will be revealed later Wednesday.

Mattison (ankle) has been ruled out for Saturday's game in Cincinnati.

Mattison sustained a sprained right ankle on the Vikings' first offensive play of the second half this past Sunday in Las Vegas. The severity of the issue hasn't been revealed, but he was unable to practice this week and thus will miss his first game of the season. Mattison will yield Minnesota's backfield to Ty Chandler in Week 15 and potentially beyond that point.

Mattison (ankle) isn't practicing Wednesday, Alec Lewis of The Athletic reports.

Ty Chandler took 79 percent of Minnesota's offensive snaps in the second half of Sunday's 3-0 win over the Raiders, stepping in as the lead back after Mattison left early with an ankle injury. The Vikings listed Mattison as a non-participant on Tuesday's practice estimate and now are holding him out of an actual practice, making him uncertain to play this Saturday against the Bengals. Kene Nwangwu is the third RB on Minnesota's active roster, but he's mostly been used on special teams throughout his career, so Myles Gaskin or DeWayne McBride may be elevated from the practice squad for the No. 2 RB role if Mattison doesn't end up playing Saturday.

Mattison (ankle) was listed as a non-participant on Tuesday's practice estimate.

Mattison racked up 66 yards on 10 carries in Sunday's 3-0 win over the Raiders before exiting with a right low-ankle sprain. His estimated non-participation on Tuesday's report isn't a great sign for his early prospects of playing Saturday against the Bengals, but more clarity on Mattison's status will be gained as the week progresses. Ty Chandler would likely be in line to handle a lead role out of the Minnesota backfield if Mattison is unable to play this weekend.

Coach Kevin O'Connell said after Sunday's 3-0 win over the Raiders that Mattison is dealing with a sprained ankle, Ben Goessling of the Star Tribune reports.

Mattison exited in the second half after racking up 66 rushing yards on 10 carries. His return timetable will hinge on the severity and location of the sprain, as low-ankle sprains often take no more than two weeks to come back from, while high-ankle sprains usually result in multi-week absences. Ty Chandler would be in line to handle the majority of snaps in Minnesota's backfield if Mattison misses additional time.

Mattison sustained an ankle injury during Sunday's game at Las Vegas, Alec Lewis of The Athletic reports.

It's been a rough injury day for the Vikings, who have lost top wide receiver Justin Jefferson (chest), starting right tackle Brian O'Neill (ankle) and now their No. 1 running back. Mattison got injured on the team's first offensive play of the second half, and if he's unable to reenter the contest, he'll end Week 14 with 10 carries for 66 yards. Ty Chandler took over Minnesota's backfield after Mattison's departure.

Mattison rushed 10 times for 52 yards and secured both targets for 11 yards in the Vikings' 12-10 loss to the Bears on Monday night. He also fumbled once but recovered.

Mattison led the Vikings in rushing yards and averaged over 5.0 yards per carry for just the second time this season with the help of a 21-yard run. The veteran back also saw two targets for the fourth straight contest, and his rushing yardage total qualified as his second highest since Week 4. Mattison notably outpaced Ty Chandler by six carries, sending him into the Week 13 bye in control of the No. 1 running back role before a favorable Week 14 road matchup versus the Raiders.

Mattison rushed 18 times for 81 yards and brought in his only target for minus-1 yard in the Vikings' 21-20 loss to the Broncos on Sunday night. He also lost a fumble.

Mattison got off to a hot start before his efficiency waned some late, but he still finished with his highest rushing yardage total since Week 4. The fifth-year pro's fumble was also costly, as it came on the Broncos' 35-yard line and led to a Denver field goal. On the brighter side, Mattison made a remarkably quick recovery from his Week 10 concussion to suit up Sunday night and outpaced backfield mate Ty Chandler by eight carries, seemingly keeping his hold on the No. 1 running back job secure heading into a Week 12 home matchup against the Bears on Monday night, Nov. 27.

Mattison (concussion) is active for Sunday's contest at Denver.

Mattison left last Sunday's win against the Saints in the third quarter due to a concussion, but he made quick progress through the protocol for head injuries, including a full practice Friday and a declaration from coach Kevin O'Connell that same day that the Vikings expected the running back to gain clearance soon from an independent neurologist, per Ben Goessling of the Minneapolis Star Tribune. With his status confirmed for Sunday Night Football, Mattison now may have to contend with fellow running back Ty Chandler for work after the latter had 15 carries for 45 yards and one touchdown Week 10.

Mattison (concussion) is expected to play Sunday night against the Broncos, Ian Rapoport of NFL Network reports.

Mattison exited Week 10 and spent much of the past week in the league's concussion protocol, but he was able to practice fully Friday after a limited session Thursday. With Mattison likely to be active, Ty Chandler will handle change-of-pace duties alongside him, leaving Kene Nwangwu mainly handling special teams work.

Mattison (concussion) is listed as questionable for Sunday's game in Denver.

Mattison departed the Vikings' Week 10 win against the Saints due to a concussion, and after sitting out Wednesday's session and returning as a limited practice participant one day later, he has a chance to miss no games as a result. Coach Kevin O'Connell even told Ben Goessling of the Minneapolis Star Tribune that Mattison likely will gain clearance from an independent neurologist Friday, but that has yet to come to pass. Assuming he's able to suit up this weekend, Mattison should be good for his typical 15.4 touches per game.

Mattison (concussion) practiced in a limited capacity Thursday.

Mattison was estimated as a non-participant on Wednesday's practice report due to the concussion that knocked him out of this past Sunday's win against the Saints. One day later, he displayed some progress through the protocol for head injuries with a capped session. Mattison thus has only one more chance to get back to all activity this week, and he'll have the added step of needing to gain clearance from an independent neurologist in order to play Sunday at Denver. If Mattison is sidelined this weekend, Ty Chandler, Kene Nwangwu and potentially practice-squad member Myles Gaskin will be the beneficiaries out of the Vikings backfield.

Mattison (concussion) was listed as a non-participant on Wednesday's practice estimate.

Mattison departed this past Sunday's win against the Saints with a head injury and eventually was confirmed to be in the concussion protocol Monday. With no on-field work to speak of to begin Week 11 prep, he doesn't appear to be in a great spot ahead of Sunday's game at Denver. If Mattison is unable to gain clearance from an independent neurologist by Saturday, the Vikings may be forced to use the combination of Ty Chandler and Kene Nwangwu out of their backfield this weekend.

Mattison is in the league's concussion protocol Monday, Alec Lewis of The Athletic reports.

Mattison left Sunday's game against the Saints in the third quarter and never returned to action. With Cam Akers (Achilles) already done for the rest of the season, the Vikings are left with Ty Chandler, Kene Nwangwu and Myles Gaskin in the backfield if Mattison is unable to play in Week 11 against the Broncos.

Mattison won't return to Sunday's game against the Saints after sustaining a concussion in third quarter, Alec Lewis of The Athletic reports.

Mattison reeled in one of two targets for six yards and carried seven times for 24 yards before suffering the head injury on a three-yard gain on what proved to be his final tote of the day. Ty Chandler -- who had moved up to No. 2 on the depth chart in the wake of Cam Akers suffering a season-ending Achilles injury last week -- will finish Sunday's contest as the Vikings' top back.

Mattison could take on a larger share of the Vikings' running backs snaps beginning in Sunday's game against the Saints after Cam Akers suffered a season-ending Achilles tear in Minnesota's Week 9 win over Atlanta, Kevin Seifert of ESPN.com reports.

Mattison had already started all nine of Minnesota's games to date, but he had seen his snap share trend downward since the Vikings acquired Akers from the Rams on Sept. 21. After playing north of 70 percent of the snaps in each of the Vikings' first three contests, Mattison cleared that bar just once in the subsequent six games while Akers averaged 8.2 touches per contest during that stretch. The Vikings are expected to break in Ty Chandler as their new No. 2 back, but given that Chandler has largely been relegated to special-teams work through his first two NFL seasons, he may not be a good bet to immediately assume Akers' vacated touches. With that in mind, Mattison could take on workloads closer to what he handled from Weeks 1 through 3, though fantasy managers shouldn't count on him to be efficient with his opportunities. Mattison is averaging just 3.6 yards per carry on the season and has yet to score a rushing touchdown, though he's been more productive as a receiver (23-158-3 line on 34 targets).

Mattison rushed the ball 16 times for 44 yards in Sunday's 31-28 win over Atlanta. He added two catches on two targets for 49 yards and a touchdown.

Mattison led the backfield with 18 touches as compared to 10 for Cam Akers (Achilles). He wasn't particularly effective on the ground -- he averaged only 2.8 yards per carry with a long of eight -- but he accounted for Minnesota's longest play from scrimmage on a 47-yard reception. Mattison also found the end zone on a two-yard touchdown catch just before halftime. With Akers feared to have suffered an Achilles injury, Mattison could retake a more substantial portion of the workload out of Minnesota's backfield moving forward.

Mattison carried the ball 16 times for 31 yards and caught his only target for two yards in Sunday's 24-10 win over the Packers.

While his 17 touches topped Cam Akers' 10, it was the latter who punched in a six-yard TD late in the first quarter. Even if Mattison maintains his top spot in the Minnesota backfield, the upside of the whole offense suddenly looks a lot more questionable with Kirk Cousins having potentially suffered a season-ending Achilles injury Sunday. Mattison and Akers could be working with rookie QB Jalen Hall instead in Week 9 against the Falcons.

Mattison rushed eight times for 39 yards and brought in two of three targets for three yards in the Vikings' 22-17 win over the 49ers on Monday night.

Mattison outpaced backfield mate Cam Akers by eight yards while compiling a team-high total, but the latter logged two additional carries. The workload split had been much more expansive between the two in Week 6 against the Bears, when Mattison had taken 18 carries to Akers' one. Whether the drastic change Monday night is indicative of what the division of labor between the two might look like moving forward remains to be seen, but both backs will have an appealing matchup against the Packers' suspect run defense on the road Week 8.

Mattison rushed 18 times for 44 yards and brought in four of seven targets for 28 yards in the Vikings' 19-13 win over the Bears on Sunday.

Mattison notably outpaced backfield mate Cam Akers by 17 carries after there was only a three-carry difference between the two in Week 5. However, as has been the case more often than not this season, Mattison was unable to do much with his opportunities on the ground, although he did put together a solid showing as a receiver. The fifth-year back does seem to have a firm hold of the lead back job, however, but he lines up for another tough matchup against the 49ers in Week 7 on Monday night, Oct. 23.

Mattison carried the ball eight times for 26 yards and caught two of three targets for 20 yards and a touchdown in Sunday's 27-20 loss to Kansas City.

The Vikings' running game had no success on the day -- Cam Akers managed only 15 rushing yards on five carries -- but Mattison's nine-yard TD catch on a screen pass from Kirk Cousins early in the fourth quarter brought Minnesota within a score. The fifth-year RB then dropped another potential touchdown on the team's next possession, however. Mattison is still looking for his first rushing touchdown of the year to go with his two receiving TDs, but he appears to be drifting into a timeshare with Akers heading into a Week 6 clash with the Bears.

Mattison rushed 17 times for 95 yards in Sunday's 21-13 win over the Panthers. He also caught his only target for three yards.

Mattison was efficient on the ground, posting season highs in rushing yards and yards per carry. The tailback has now topped 95 scrimmage yards in consecutive games, which should help his case to maintain the Vikings' starting tailback job ahead of Cam Akers, who on Sunday finished with 51 yards on seven touches.

Mattison rushed the ball 20 times for 93 yards in Sunday's 28-24 loss to the Chargers. He added five receptions for 32 yards.

Cam Akers (coach's decision) was inactive after being acquired earlier in the week, leaving Mattison as the lead back once again. Mattison made the case to keep the role moving forward with production as both a rusher and receiver. Entering Sunday's action, he had just 62 total yards on the ground through two games, but he managed to easily surpass that mark with four of his 20 carries going for double-digit gains. Mattison also has at least four targets in every contest this season, though it remains to be seen how the Vikings plan to incorporate Akers into the offense, presumably starting in Week 4 against Carolina.

Coach Kevin O'Connell told reporters Friday that he still views Mattison as the Vikings' lead back after a recent trade for Cam Akers, who is unlikely to play this Sunday against the Chargers, Kevin Seifert of ESPN.com reports.

O'Connell went as far as saying nothing has changed for Mattison despite his rough start to the season and now the addition of a 2020 second-round pick to Minnesota's backfield. In reality, Mattison is on the hot seat, though Akers won't necessarily provide the stiffest competition given his inconsistent tenure in Los Angeles. He finished his rookie year strong and had a nice four-week stretch to close out last season, but it's otherwise been a series of demotions and subpar performances ever since he tore his Achilles in spring 2021. O'Connell said Akers won't be ready to play for his new team this Sunday, giving Mattison at least one more game with only Ty Chandler taking away any backfield snaps.

The Vikings have not lost confidence in Mattison despite Wednesday's trade for Cam Akers, offensive coordinator Wes Phillips told reporters Thursday. "Unfortunately we've had a couple turnovers in the run game where we obviously need to clean that up. Everyone's aware of that. But we still feel very strongly in Alex and [backup Ty Chandler] and those guys being able to go in and produce," Phillips told ESPN.

Mattison has had a slow start to the season with two lost fumbles in Week 2 and just 62 yards rushing on 19 carries for a paltry 3.3 YPC. Akers may not play much this week against the Chargers as he gets up to speed on the offense, but could quickly move past Ty Chandler for the backup role. Given Mattison's struggles, it's not hard to envision Akers moving into a time share with Mattison. However, Akers still has much to prove after his own underwhelming performance this season (29 yards rushing on 22 attempts in Week 1).

Mattison rushed eight times for 28 yards and brought in three of six targets for 11 yards in the Vikings' 34-28 loss to the Eagles on Thursday night. He also lost a fumble.

Mattison had what had to be considered a second straight disappointing performance to open the season, finding running room at a premium for the most part and then also seeing his overall opportunities limited by game script. The fifth-year pro was also fortunate his first-quarter fumble didn't lead to any points, as the Eagles' Justin Evans recovered at the Vikings' 39-yard line. Mattison has garnered less than 35 rushing yards in each of his first two games as Minnesota's unquestioned lead back, leaving him with little momentum heading into what could be a solid Week 3 home matchup against the Chargers on Sunday, Sept. 24.

Mattison rushed 11 times for 34 yards and brought in three of four targets for 10 yards and a touchdown in the Vikings' 20-17 loss to the Buccaneers on Sunday.

Playing his first game as the Vikings' unquestioned lead back, Mattison came up considerably short statistically overall, even when factoring in his early-fourth-quarter receiving touchdown. The fifth-year back was repeatedly stifled by a traditionally tough Buccaneers run defense, so perhaps the highly inefficient performance -- which featured a long run of just nine yards -- will prove to be an outlier over time. However, Mattison doesn't exactly get a reprieve in his Week 2 matchup, a road date with the Eagles on a short week Thursday night.

The Vikings enter Week 1 with only Ty Chandler and Myles Gaskin behind Mattison on the depth chart, the Star Tribune reports.

Mattison dealt with a minor injury in early August and didn't play in any preseason games, but he's been back in practice for a while now and is all set to lead the Minnesota backfield Week 1 against Tampa Bay. The extent of his workload remains to be seen, with a dominant share one of the possibilities given that Chandler and Gaskin are late-round picks in their mid-20s who combined for 20 touches last season. Both seem most likely to take playing time from Mattison in passing situations, if at all.

Mattison (undisclosed) did not play in Saturday's 18-17 preseason loss to the Cardinals.

Mattison has been dealing with an undisclosed injury that has kept him out of preseason action. The Vikings are likely being precautious with him given his status as the team's lead back, though practice reports in the leadup to a Week 1 matchup against the Buccaneers will ultimately provide more information about his health.

Mattison (undisclosed) took part in Thursday's practice, Andrew Krammer of the Minneapolis Star Tribune reports.

After Mattison missed the final stages of Tuesday's session while sporting a limp, he's been able to handle reps in back-to-back days. Wednesday's practice was a walkthrough, while the Vikings were back to a normal version Thursday, so he appears to be putting the injury behind him. Reserve running back Kene Nwangwu also is dealing with an unknown injury at the moment, so Minnesota signed Abram Smith on Thursday to bolster its backfield depth alongside Ty Chandler and rookie seventh-round pick DeWayne McBride.

Mattison (undisclosed) is participating in Wednesday's walkthrough, Andrew Krammer of the Minneapolis Star Tribune reports.

While a walkthrough doesn't entail contact or sprinting, Mattison's participation nonetheless indicates that the injury he suffered Tuesday isn't too serious. He was seen limping near the end of practice, which left Ty Chandler and DeWayne McBride as the only healthy tailbacks with Kene Nwangwu (undisclosed) already sidelined. Mattison's spot atop the depth chart seems more solid than ever, as the Vikings still haven't signed a veteran running back and reportedly haven't received great performances from their young backups this summer (per Alec Lewis of The Athletic).

Mattison (undisclosed) was seen limping near the end of Tuesday's practice, Alec Lewis of The Athletic reports.

The nature of Mattison's potential injury isn't known, but he observed the latter stages of the session from the sideline before making his way to the locker room, per Kevin Seifert of ESPN.com. Kene Nwangwu also didn't log any on-field work for a second consecutive day, which left plenty of RB reps for Ty Chandler and rookie seventh-rounder DeWayne McBride. There's a good chance coach Kevin O'Connell gives an update on the state of the Vikings backfield in the near future, but for now Mattison's status is unclear.

Offensive coordinator Wes Phillips said Thursday that Mattison "always knows what he's going to do" and is a better player than people realize, Ben Goessling of the Star Tribune reports.

Mattison ran a 4.67 40-yard dash coming out of Boise State in 2019 and didn't have a single 20-yard gain on 89 touches last year, but what he lacks in explosiveness he arguably makes up for with versatility, having proven himself competent as a blocker and pass catcher while also possessing the size and strength to handle large rushing workloads. Although Phillips acknowledged that the Vikings will miss Dalvin Cook's big-play ability, the OC seemed to hint that Mattison should do a better job keeping the offense on schedule and avoiding runs for no gain or lost yardage. Whether that's true remain to be seen, but it's at least clear the Vikings have confidence in Mattison, as they re-signed him to a two-year, $7 million contract and still haven't added a veteran RB to compete for carries. In fact, they're the only team in the NFL with fewer than five tailbacks on the roster at the start of training camp, with Mattison joined by 2021 fourth-round pick Kene Nwangwu, 2022 fifth-round pick Ty Chandler and 2023 sev

Mattison becomes the incumbent No. 1 option in Minnesota's backfield after the team informed Dalvin Cook (shoulder) on Thursday of his coming release, Adam Schefter of ESPN reports.

Mattison re-signed with the Vikings on a two-year contract this offseason, a move which now positions him as the likely starter heading into 2023. The 2019 third-round pick has flashed in his previous four years with Minnesota when asked to fill in for Cook, averaging 4.1 career yards per carry while also securing 70 of 84 targets for 526 yards. Ty Chandler and rookie seventh-round pick DeWayne McBride could also potentially earn weekly touches, though Kene Nwangwu mostly profiles as a special-teams option, leaving the Vikings without much in the way of proven depth behind Mattison. While the team could still add to the backfield ahead of Week 1, Mattison currently faces massive opportunity and is a lock to rocket up fantasy draft boards.

The Vikings and Mattison agreed to terms on a two-year contract Wednesday, Tom Pelissero of NFL Network reports.

Mattison has played second fiddle to fellow running back Dalvin Cook for his entire four-year career, but the former has had a handful of chances to shine, starting six of his 59 appearances. Overall, Mattison has averaged just 4.1 yards per carry and scored 14 touchdowns, but he's also reeled in 70 of 84 targets for 526 yards, good for an 83.3 percent catch rate. There have been rumblings this offseason that the Vikings may be willing to part ways with Cook, so Mattison could benefit in 2023 if the structure of the team's backfield is altered in the coming months.

Mattison rushed 10 times for 54 yards and two touchdowns in Sunday's 29-13 win over the Bears.

Mattison's season-best performance included a pair of one-yard touchdowns. With Minnesota opting to rest its starters during the second half, Mattison filled Dalvin Cook's lead tailback role to begin the third quarter. Once the Vikings take the field in the playoffs, however, Mattison should return to his usual backup job.

Mattison had eight carries for 38 yards and had one reception for seven yards in Sunday's loss at Green Bay.

Mattison played 23 snaps on offense as he got more work once the game became a blowout. He could get significant time or even start Week 18 against the Bears if the Vikings decide to rest starters head of the playoffs.

Mattison rushed four times for 17 yards in Saturday's 27-24 win over the Giants.

Mattison earned just a 21 percent offensive snap share in the contest, while Dalvin Cook played 79 percent of snaps at running back. With Cook healthy and playing well, Mattison has been nothing more than a handcuff for fantasy purposes seeing minimal involvement on offense. This should remain true as the Vikings visit the Packers in Week 16.

Mattison rushed twice for one yard and wasn't targeted in Saturday's 39-36 overtime win over the Colts.

Minnesota didn't find many touches for Mattison while a healthy and effective Dalvin Cook played a key role in the team's historic comeback from a 33-point deficit. Cook totaled 190 scrimmage yards and a touchdown on 21 touches. With the 49ers hot on Minnesota's heels for the No. 2 seed in the NFC, the Vikings many need to keep riding Cook through the remainder of the season, leaving Mattison stapled to the bench for the majority of snaps.

Mattison lost a yard on two carries in Sunday's loss at Detroit.

Mattison played just nine snaps on offense and was not targeted in the passing game as he had a minimal role with the Vikings falling behind early and needing to pass. Mattison continues to operate strictly as the backup to Dalvin Cook. Though Mattison is capable of making big plays, he has earned fewer than three carries in six consecutive games.

Mattison rushed the ball three times for 14 yards and a touchdown in Sunday's 27-22 win over the Jets. He added two receptions for four yards.

Mattison continued to operate strictly as the backup to Dalvin Cook. However, he managed to make an impact with his limited opportunity by ripping off a 14-yard touchdown late in the second quarter. Though Mattison is capable of making big plays, he has earned fewer than three carries in five consecutive games -- making him difficult to trust for fantasy purposes.

Mattison rushed twice for no gain and caught his only target for eight yards in Sunday's 40-3 loss to the Cowboys.

As usual, Mattison didn't get many touches. Nobody on the Vikings played particularly well, though Dalvin Cook actually rushed for a respectable 72 yards on 11 carries, showing why Cook gets the majority of opportunities in Minnesota's backfield when healthy. The Vikings won't have to dwell on this blowout loss long, as they'll be right back in action Thursday against the Patriots on Thanksgiving.

Mattison had three carries for 11 yards and one reception for eight yards on his lone target in Sunday's win at Buffalo.

Mattison played on 12 off the offense's 80 snaps (15%), seeing time on one drive to give starter Dalvin Cook a break. His snap share has trended downward this season with 24 percent or less the past four games, giving him little fantasy value barring a Cook injury. Mattison still is one of the more valuable backup running backs in the league given his production when thrust into the starting lineup.

Mattison gained one yard on two carries and had one reception for no yards on his only target in Sunday's win at Washington.

Mattison played on just nine of the offense's 66 snaps (14%) as he had a limited backup role behind a healthy Dalvin Cook. Mattison's snap share has trended downward this season with 24% or less the past three games, giving him little fantasy value barring a Cook injury. He's still one of the more valuable backup running backs in the league given his production when thrust into a starting role.

Mattison rushed five times for 40 yards and a touchdown in the Vikings' 34-26 win over the Cardinals on Sunday.

The accomplished backup made excellent use of his scant opportunity, ripping off a 15-yard gain on one of his five carries and contributing a seven-yard touchdown run on another tote. Mattison's score was his second on the ground this season, and the five touches on the ground were a welcome sight after he'd logged a season-low one against the Dolphins back in Week 6 prior to the bye.

Mattison (shoulder) logged three yards on his lone carry and played just six of the Vikings' 50 snaps on offense in Sunday's 24-16 win over the Dolphins.

Listed as questionable heading into Sunday, Mattison was cleared to play but handled a more limited role than usual while nursing a shoulder injury. The Vikings leaned more heavily on lead back Dalvin Cook (88 percent snap share, 14 touches for 83 yards and a touchdown) as a result, while Mattison played his fewest snaps of the season. Assuming he escaped the contest with no further setbacks to his shoulder, Mattison should see his opportunities pick up in the weeks to come. When he was healthier in the Vikings' first five games, Mattison took on snap shares between 23 and 46 percent.

Mattison is active for Sunday's matchup against the Dolphins.

Mattison picked up a shoulder injury during the Vikings' Week 5 win over the Bears and was limited at each practice ahead of Week 6, earning him a questionable designation. As expected, the backup running back will be available, but it's unclear how much work he'll get behind Dalvin Cook. Mattison turned a season-high 12 touches into 40 scrimmage yards last week and has totaled 37 touches for 154 yards and two scores across five appearances this year.

Mattison (shoulder), officially listed as questionable for Sunday's game against the Dolphins, is expected to play, Jeremy Fowler of ESPN.com reports.

Mattison logged limited practices all week after suffering the injury in Minnesota's Week 5 win over Chicago. He earned a season-high 12 touches in that game but could see his workload scaled back moving forward as Dalvin Cook remains the clear lead back in Minnesota. Mattison's status will become official just prior to the 1 PM ET kickoff Sunday.

Vikings head coach Kevin O'Connell said Mattison (shoulder) will be listed as questionable for Sunday's game against the Dolphins, Alec Lewis of The Athletic reports.

According to Ben Goessling of the Minneapolis Star Tribune, O'Connell thinks Mattison will be able to suit up Sunday, but official confirmation on the running back's status won't come one way or the other until the Vikings release their inactive list 90 minutes prior to the 1 p.m. ET kickoff. If available, Mattison should handle his usual complementary role behind Dalvin Cook, though Mattison could see at least a slight drop from the season-high 46 percent snap share and 12 touches he took on during last week's win over the Bears.

Mattison (shoulder) practiced in a limited capacity Thursday.

Mattison maintained his activity level from Wednesday's session, giving him just one more opportunity to get back to full this week. Even if he enters the weekend with a game-day designation, there's been no indication that he's in danger of sitting out Sunday at Miami. Assuming he's available, Mattison would be poised for modest work behind starting running back Dalvin Cook, which has amounted to 7.4 touches for 30.4 yards from scrimmage per game and two total TDs across five contests this season.

Mattison (shoulder) was a limited participant in practice Wednesday.

Mattison played a season-high 43 percent of snaps in a Week 5 win over Chicago, though his 12 touches netted only 41 yards, while Dalvin Cook took 20 touches for 121 yards and a pair of touchdowns. Mattison has seen a bit more work than in past years ever since Cook dislocated his problematic shoulder, but the starter hasn't missed a game yet and it's now the backup who is bothered by a shoulder injury. In any case, Mattison's practice participation Wednesday -- even in a limited capacity -- suggests he's more likely than not to play this Sunday in Miami.

Mattison had nine carries for 19 yards and three receptions for 21 yards on four targets in Sunday's win over Chicago.

Mattison played on a season-high 46% of the offensive snaps (34 snaps) and got a decent workload even with Dalvin Cook having a strong game (18 carries for 94 yards and two receptions). However, it is hard to count on a workload even this large unless Dalvin Cook gets hurt.

Mattison had three carries for three yards and one reception for a 15-yard touchdown on his lone target in Sunday's win over New Orleans in London.

With Dalvin Cook able to play despite a shoulder injury, Mattison returned to his reserve role and played about the usual number of snaps. Cook's chronic dislocated shoulder issue didn't appear to have any setback, so Mattison should have a reserve role again next week against Chicago.

Mattison carried the ball seven times for 28 yards and a touchdown in Sunday's 28-24 win over the Lions. He added one reception for 16 yards.

Mattison settled into his typical change of pace role and had only four carries through three quarters. However, he served as the Vikings' lead back in the final quarter of the game after Dalvin Cook exited with a shoulder injury. Though Mattison didn't get a ton of volume, he made a large impact with a 16-yard reception and trip to the end zone from six yards away. Cook was diagnosed with a dislocated shoulder after the game, so there is a chance that Mattison will get lead-back duties in a Week 4 matchup at New Orleans.

Mattison had two carries for eight yards and three receptions for six yards in Monday's loss at Philadelphia.

Mattison played on 19 of the offense's 61 snaps and wasn't involved much, which isn't surprising given the Vikings were playing from a large deficit most of the game. It looks like Mattison will have the same role as prior years with a large role if Cook is hurt, but a modest one if the latter is healthy.

Mattison had eight carries for 36 yards but no receptions in Sunday's win over Green Bay.

Mattison played on 14 of the offense's 62 snaps, essentially giving starter Dalvin Cook rest on two series. Even with new head coach Kevin O'Connell, the workload split between Cook (48 snaps) and Mattison remained about the same as last season. It looks like Mattison will have the same role as prior years with a large role if Cook is hurt, but a modest role if he's healthy.

Mattison (personal) doesn't have a designation for Sunday's game against the Packers.

Mattison was absent from practice Thursday due to a personal matter, but coach Kevin O'Connell told asdf on Friday that the Vikings expect the running back to be available for Week 1 action. With Dalvin Cook taking up the vast majority of running back reps for the team, Mattison can't expect more than a handful of touches in the season opener, barring an injury to the former.

Mattison didn't practice Thursday due to personal reasons.

There's been no indication Mattison is in danger of not suiting up Sunday against the Packers, but Friday's practice report could be telling in that regard. Assuming he plays this weekend, he'll serve as the Vikings' primary backup to starting running back Dalvin Cook, which typically only equates to a handful of touches as long as the workhorse is healthy.

Mattison has been the subject of trade discussions with "at least 12" teams, according to Chris Tomasson of the St. Paul Pioneer Press.

The 2019 third-round pick is in the final season of his rookie contract and doesn't plan to sign an extension with the Vikings. Mattison isn't likely to get more than 5-7 touches per game when the team has Dalvin Cook, who missed multiple contests in each of his first five seasons. Cook's shoulder is particularly vulnerable to re-injury after numerous sprains and dislocations, but he seems to be healthy heading into a Week 1 joust with the Packers.

Mattison recorded three carries for 17 yards in Saturday's preseason loss to the 49ers.

Mattison was the starting back with Dalvin Cook (rest) out, though he didn't tally a carry after Minnesota's first offensive possession. He ripped off a 13-yard gain that pushed the Vikings deep into San Francisco territory, though the drive ended with a Kellen Mond interception. Mattison will continue to work as Cook's backup once the regular season kicks off.

Mattison started Sunday's preseason tilt against the Raiders in place of Dalvin Cook (hand/rest), finishing with three carries for eight yards and no targets in the passing game.

Cook's hand injury isn't expected to jeopardize his Week 1 status, so fantasy managers do not need to read too much into Mattison starting this contest. The fourth-year back has proven to be a reliable fantasy asset when asked to fill in for the oft-injured Cook in the past, but Mattison's role nearly vanishes when the Vikings' star is at full strength. For leagues that have drafted already, Mattison could be worth holding onto until we see Cook officially enter one of Minnesota's remaining two preseason games.

Mattison (finger) practiced Wednesday, Arif Hasan of The Athletic reports.

Mattison and Dalvin Cook (hand) both practiced Wednesday after suffering minor injuries Tuesday. The pecking order in Minnesota appears the same as ever, though a new coaching staff could mix things up a little by giving Kene Nwangwu or Ty Chandler a few looks. Still, it's mostly the same deal for Mattison in the fourth and final year of his rookie contract, with fantasy value largely tied to Cook's health.

Mattison appeared to injure a finger during Tuesday's practice and left early, the Minneapolis Star Tribune reports.

The injury appears minor, but it's worth monitoring during training camp. Mattison will reprise his role as the backup to starter Dalvin Cook. He's one of the better backups in the league as in four games as the primary running back last season with Cook sidelined, Mattison totaled 356 rushing yards, 162 receiving yards and three touchdowns. However, he had just 135 yards rushing in the 12 games where he served as the backup. It's possible new head coach Kevin O'Connell could look to give Cook more rest this year, but even then we wouldn't expect a significant increase in Mattison's touches when serving as the backup.

Mattison ran five times for 18 yards and caught his only target for three yards during Week 18's 31-17 win over the Bears.

With Dalvin Cook healthy, Mattison once again took a back seat in Week 18. He finished the 2021 campaign with 134 rushing attempts for 491 yards and three touchdowns while adding 32 receptions for 228 yards and one score through the air. However, the majority of that production came when Cook was sidelined. In four games as the primary running back, Mattison totaled 356 rushing yards, 162 receiving yards and three touchdowns. The 2019 third-round pick is under contract for the 2022 season, so he'll likely garner a similar backup role to Dalvin Cook again next year.

Mattison did not have a carry and had four receptions for 13 yards on five targets in Sunday's loss at Green Bay.

Mattison returned to a backup role with Dalvin Cook returning from the COVID-19 list after missing a game. Mattison played on 19 of the offense's 54 snaps. It's possible Mattision could have a larger role Week 18 against Chicago with Minnesota out of the playoff race and the team potentially resting Cook.

Mattison rushed the ball 13 times for 41 yards and a touchdown in Sunday's 30-23 loss to the Rams. He added three receptions for 29 yards.

Mattison dominated touches out of Minnesota's backfield in the absence of Dalvin Cook (illness), accounting for 13 of 22 total rushes -- four of which were recorded by Kirk Cousins. However, he was held in check for much of the game, though he managed a two-yard touchdown plunge early in the third quarter to turn in a productive performance from a fantasy perspective. He was also fairly active as a receiver, which also supplemented his subpar work as a rusher. It's unclear whether Cook will be back for Minnesota's Week 17 matchup against Green Bay, but if not Mattison will once again be in line for a significant workload.

Mattison is on track to serve as Minnesota's lead back Sunday against the Rams after Dalvin Cook was placed on the reserve/COVID-19 list Thursday, Chris Tomasson of the St. Paul Pioneer Press reports.

The Vikings haven't revealed whether Cook was placed on the list due to a positive test for the virus, but because he's unvaccinated, the 26-year-old running back will have to complete a five-day quarantine even if he was deemed a close contact of an infected person. If he tested positive for the virus, Cook would be subject to a 10-day quarantine, which would provide him with enough time to get cleared ahead of a Jan. 2 game against the Packers in Week 17, albeit without the benefit of any practice beforehand. In any case, since he'll be picking up at least one start sans Cook, Mattison looks like a strong lineup option in just about any fantasy format. In his prior three starts while Cook was sidelined Weeks 3, 5 and 13, Mattison played at least two-thirds of the Vikings' offensive snaps and averaged 24.3 carries, 6.0 targets and 149.3 yards from scrimmage per game while reaching the end zone twice.

Mattison (illness), whom the Vikings placed on the reserve/COVID-19 list Monday, isn't vaccinated and thus has entered into a 10-day quarantine, making him unavailable for next Monday's game at Chicago, Chris Tomasson of the St. Paul Pioneer Press reports.

Mattison returned to his complementary role out of the backfield last Thursday against the Steelers with Dalvin Cook (shoulder) back in the lineup, taking six carries for 27 yards. With Monday's development, those reps now will trickle down to Kene Nwangwu and Wayne Gallman, who was claimed off waivers Monday. Mattison's next chance to suit up will be Sunday, Dec. 26 against the Rams.

Mattison (undisclosed) was placed on the reserve/COVID-19 list Monday.

Mattison reverted to a complementary role Week 14 versus the Steelers with Dalvin Cook back on the field, and he's now entered the health and safety protocols. It's unclear whether Mattison tested positive for the virus or if he's considered a close contact, but he'll be unavailable until he clears the protocols regardless. Veteran tailback Wayne Gallman was claimed off waivers to bolster Minnesota's depth at running back in the meantime.

Mattison rushed six times for 27 yards and failed to bring in his only target during the Vikings' 36-28 win over the Steelers on Thursday night.

The talented backup running back returned to his usual spot on the depth chart since Dalvin Cook was able to overcome his shoulder injury and suit up Thursday. Cook went on to deliver the second-best rushing yardage tally of his career (205) on 20 carries, leaving Mattison with only a handful of touches in the high-scoring win. As capable as Mattison has proven to be when given extended opportunity, Thursday's results served as a tangible reminder of why Mattison will remain a clear No. 2 behind his teammate as long as Cook is healthy.

Mattison will welcome back Dalvin Cook (shoulder) to the Vikings backfield for Thursday's game against the Steelers.

Mattison is coming off his third spot start of the season for Cook in which he took 25 touches for 124 yards from scrimmage and one rushing TD during this past Sunday's loss at Detroit. With Cook back in the lineup and wearing a harness on his previously dislocated left shoulder, there's a chance Mattison spells Cook at times to ease the pressure on Minnesota's top running back. Still, when Cook has been available this season, Mattison has averaged just five touches per game.

Mattison rushed 22 times for 90 yards and a touchdown while adding three receptions for 34 yards in Sunday's 29-27 loss to the Lions.

Mattison got the start in place of the injured Dalvin Cook (shoulder), doing his best impression of Minnesota's star tailback. The 23-year-old is now averaging 149.3 combined yards and two total touchdowns in the three starts he has made this season, making him a must-roster player for any games Cook is forced to miss. While the latter was technically listed as questionable leading up to Sunday's tilt, initial reports projected Cook to miss two games. The Vikings are slated to take on the Steelers on Thursday, so Mattison could get another start with such a quick turnaround.

Mattison is expected to fill a lead role out of the Minnesota backfield Sunday in Detroit with Dalvin Cook (shoulder) ruled out for the contest, Craig Peters of the Vikings' official site reports.

Mattison already appeared to be tracking toward his third start of the season after Adam Schefter of ESPN reported Monday that Cook was due to miss the Vikings' next two games with a dislocated left shoulder, but head coach Mike Zimmer wasn't immediately willing to rule the 26-year-old out for the Week 13 matchup. Zimmer finally relented Friday after Cook missed his third straight practice, leaving Mattison and Kene Nwangwu as the lone healthy running backs currently on the 53-man roster. Given that Nwangwu has been entrusted with little more than a special-teams role this season, Mattison should be well positioned to play at least two-thirds of Minnesota's offensive snaps while likely taking on 20-plus ditches, just as he did in starts Week 3 and 5. In the Week 5 matchup with this same Lions squad, Mattison carried 25 times for 113 yards and hauled in all seven of his targets for 40 yards and a touchdown. Mattison looks like a must-start option in just about every fantasy league Week 13.

Mattison carried the ball seven times for 21 yards and a touchdown and caught two of three targets for seven yards in Sunday's 34-28 loss to the 49ers.

The touchdown, Mattison's first rushing TD of the year, came early in the second half, but Dalvin Cook left the game on the Vikings' very next drive with a shoulder injury and didn't return. If Cook's latest injury proves to be serious, Mattison could find himself back in the lead role for a very juicy Week 13 matchup with the Lions.

Mattison had three carries for five yards in Sunday's win over Green Bay.

Mattison isn't getting many opportunities with Dalvin Cook healthy, as he's had just 20 touches in his last five games. Mattison had more than 100 yards rushing in both spot starts this season when Cook was injured, so he's still one of the more valuable backups in the league.

Mattison had four carries for 16 yards and one reception for 24 yards in Sunday's win at the Chargers.

Mattison isn't getting many touches with Dalvin Cook healthy, but his 24-yard reception was a key play in the game. He played just 12 snaps on offense as he has a limited backup role with Dalvin Cook at full strength. Mattison eclipsed 100 rushing yards in both spot starts when Cook has sat out this season, so he's still one of the more valuable backups in the league.

Mattison had four carries for a total of no yards and one reception on his lone target for three yards in Sunday's loss at Baltimore.

Mattison played just nine snaps as he has a limited backup role with Dalvin Cook at full strength. Mattison eclipsed 100 rushing yards in both spot starts when Cook has sat out this season, so he's one of the more valuable backups in the league.

Mattison had two carries for five yards and lost five yards on two receptions in Sunday's loss to Dallas.

Mattison played eight snaps on offense as he had a minimal role with Dalvin Cook full healthy. Mattison eclipsed 100 rushing yards in both spot starts when Cook has sat out this season, so he's one of the more valuable backups in the league. However, he'll likely have minimal fantasy most games when Cook is healthy.

Mattison had three carries for 10 yards in Sunday's win at Carolina.

With Dalvin Cook back to full strength after missing the previous game with an ankle injury, Mattison moved back to a reserve role and played on just 12 of the offense's 89 snaps. Mattison eclipsed 100 rushing yards in both spot starts when Cook has sat out this season, so he's one of the more valuable backups in the league. However, he'll likely have minimal fantasy most games when Cook is healthy.

Mattison (shoulder) doesn't carry an injury designation into Sunday's game against the Panthers, Courtney Cronin of ESPN.com reports.

Dalvin Cook (ankle) has also been cleared, so Mattison will likely be relegated to a backup role. Mattison has eclipsed 100 rushing yards in both spot starts when Cook has sat out this season. Given Mattison's effectiveness and Cook's fragile health, Minnesota may opt to give Mattison a more significant share of the workload than he had been receiving previously with both running backs healthy.

Mattison (shoulder) practiced in a limited fashion Thursday.

A shoulder issue is impacting Mattison's practice reps during Week 6 prep, keeping him out of Wednesday's session entirely before returning to the field one day later. While Mattison increased his activity level, Dalvin Cook (ankle) did the same, as he went from limited to full in the same time span. The development would appear to set Cook up to retain the No. 1 role out of the Vikings backfield, meaning Mattison would be his top reserve, at best, if he's able to suit up Sunday at Carolina.

Mattison (shoulder) returned to practice Thursday, Chad Graff of The Athletic reports.

After logging a DNP to begin Week 6 prep, Mattison seemed to be matching what Dalvin Cook (ankle), who was limited Wednesday, did one day later. If both end up with LP next to their names on Thursday's injury report, the Vikings could be trending toward a direction where it's the status quo for their backfield Sunday at Carolina, with Cook as the No. 1 and Mattison on hand as his top backup. In any case, the activity level for Cook and Mattison will be known later Thursday.

Mattison was a non-participant at Wednesday's practice due to a shoulder injury.

Mattison has filled in admirably for Dalvin Cook (ankle) during recent absences in Weeks 3 and 5, racking up at least 150 yards from scrimmage on both occasions and recording a receiving touchdown in the latter contest. Now, Mattison seems to be less healthy than Cook, as he didn't do more than take part in stretching before heading indoors at the start of practice Wednesday, according to Courtney Cronin of ESPN.com. As for Cook, he officially was limited to begin Week 6 prep, so this situation bears monitoring as the week goes on to get a bearing on who among the two will be available Sunday in Carolina.

Mattison will be the Vikings' lead running back Sunday versus the Lions with Dalvin Cook (ankle) inactive, Courtney Cronin of ESPN.com reports.

This will mark Mattison's second spot start of the campaign in place of Cook. In Week 3, Mattison was a workhorse against the Seahawks, turning 26 carries into 112 yards and six catches (on eight targets) into 59 yards. He has a good matchup on tap in which to produce this time around, too, as Detroit's defense has given up 134.8 yards from scrimmage per game and nine total TDs to running backs in four contests this season.

Mattison rushed 10 times for 20 yards and didn't draw a target in the Vikings' 14-7 loss to the Browns on Sunday.

Dalvin Cook was active and logged nine carries along with six targets, so he was more involved overall than Mattison. However, Mattison did pace the duo in rushing workload, a development that may well have been tied to Cook playing on an ankle that still wasn't 100 percent after only a one-week absence. Mattison could well return to his more customary complementary role in a Week 5 home matchup versus the Lions.

Mattison is expected to serve as the Vikings' No. 2 option out of the backfield Sunday against the Browns with Dalvin Cook (ankle) considered likely to play after missing Minnesota's Week 3 win over the Seahawks, Adam Schefter of ESPN reports.

Cook was a limited participant in practice throughout the week and remains listed as questionable for the contest, but he's expected to avoid the inactive list, which the Vikings will release 90 minutes prior to the 1 p.m. ET kickoff. Assuming that's the case, Cook should take back starting duties for the Vikings, though he could handle a lighter workload than normal if Minnesota is keen on easing him back in from the ankle injury. With that in mind, Mattison doesn't look like a bankable fantasy option if Cook is active, even though the Boise State product is coming off an impressive Week 3 outing in which he finished with 112 yards on 26 carries and 59 yards on six receptions.

Mattison carried the ball 26 times for 112 yards and caught six of eight targets for 59 yards in Sunday's 30-17 win over the Seahawks.

With Dalvin Cook (ankle) sidelined, Mattison stepped into the lead role in the Minnesota backfield and put up a very Cook-like performance, proving to be effective as both a runner and receiver. The third-year back is more than capable of delivering big numbers when called upon, but his fantasy value will depend on Cook's health heading into a Week 4 clash with the Browns.

Mattison is starting in place of Dalvin Cook (ankle) on Sunday against the Seahawks, Eric Smith of the Vikings' official site reports.

Cook will sit at least one game due to the ankle sprain he picked up Week 2, allowing Mattison a spot start. When Cook went down with a groin injury Week 5 of last season in Seattle, Mattison put together the only 100-yard rushing performance of his career, totaling 112 yards on the ground and 24 more yards as a receiver. With just Ameer Abdullah and fullback C.J. Ham to contend with for touches, Mattison could be poised for another fruitful outing Sunday.

Mattison could have a big opportunity Sunday, as the Vikings are pessimistic about Dalvin Cook (questionable - ankle) suiting up for their game against the Seahawks, Ian Rapoport of NFL Network reports.

Cook is a game-day decision and could have a limited role even if he's active. Last year, Mattison had one dud (Week 6) and one huge performance (Week 17) in his two fill-in starts, and he should handle a large workload Sunday if Cook doesn't end up playing. Ameer Abdullah is the only other tailback on Minnesota's roster for Sunday's game, with the team opting not to call up preseason star A.J. Rose from the practice squad.

Mattison had three carries for 11 yards and one reception for 17 yards on his only target in Sunday's loss to Arizona.

Mattison played 13 snaps on offense, slightly up from nine snaps last week, but had four touches compared to two last week. He'll have a minimal role as long as Dalvin Cook is healthy. However, Mattison's workload could increase in Week 3 if the sprained ankle that Cook suffered Sunday limits his snaps.

Mattison had one carry for two yards and one reception for four yards in Sunday's loss at Cincinnati.

Mattison played just nine snaps on offense as the Vikings used the running game sparingly when falling behind early. Mattison may get more involved if the Vikings are ahead and running the ball more often, but he won't get significant touches without a Dalvin Cook injury.

Mattison (ribs) practiced in full Wednesday, Craig Peters of the Vikings' official site reports.

Mattison lasted just two offensive snaps for the Vikings in preseason Week 2 and has been sidelined from practice for most of the intervening period. Now that he's back on the field and uninhibited, though, he's set to serve as Dalvin Cook's primary reserve for a third straight season. In the previous two, Mattison averaged 8.4 touches for 42.4 yards from scrimmage per game while scoring four TDs in 26 appearances.

Mattison (undisclosed) is not practicing Wednesday, Dane Mizutani of the Pioneer Press reports.

Mattison has been sidelined with an undisclosed issue since Aug. 23, and the nature and severity of his injury remains undisclosed. With less than two weeks remaining before Sept. 12's season opener in Cincinnati, Mattison's status will warrant close monitoring. With Kene Nwangwu (knee) also not practicing, starter Dalvin Cook is currently the only healthy running back on the Vikings' roster.

Mattison (undisclosed) didn't practice Monday, Courtney Cronin of ESPN.com reports.

Mattison may have been injured in the Vikings' second preseason game, as he logged just two snaps and hasn't practiced since. He did watch Monday's practice from the sideline, whereas some of the players with more serious injuries weren't present at all. Assuming he makes it back on the practice field soon, Mattison is locked in as Minnesota's No. 2 back behind Dalvin Cook ahead of a Sept. 12 opener against Cincinnati. Last year, Mattison averaged 4.5 carries and 0.7 targets in the 10 full games he and Cook played together.

Mattison (undisclosed) rode a stationary bike on the side during Wednesday's practice, Eric Smith of the Vikings' official site reports.

Mattison initially missed practice Monday and now seems unlikely to play in Friday's preseason game against the Chiefs. After that, he'll have 16 days to prepare for Minnesota's Sept. 12 opener against Cincinnati, gearing up for his familiar role as Dalvin Cook's backup. The Vikings did use a fourth-round pick on Kene Nwangwu this spring, but he's a raw prospect in the first place and has now been out since mid-August with a hyperextended knee. If Mattison is unexpectedly slow to recover from his current issue, the Vikings can turn to Ameer Abdullah, Ito Smith or A.J. Rose for Week 1 backup snaps.

Mattison did not practice Monday due to an undisclosed injury, Chad Graff of The Athletic reports.

Mattison played just two plays in Saturday's preseason game, but no injury was reported after the game. With Kene Nwangwu and Mattison hurt, the Vikings signed Ito Smith on Monday to help with depth.

Mattison didn't have a carry and caught both of his targets for 16 yards during Saturday's preseason defeat to the Colts.

With Dalvin Cook unavailable, Mattison interestingly was on the receiving end of Kirk Cousins' first two passes, but when the Vikings went to the ground Ameer Abdullah garnered the first two rushes. Afterward, Mattison didn't see another touch, while Abdullah got work with both the starters and reserves until halftime. Mattison has a firm hold on the backup RB job to Dalvin Cook, so the former's usage Saturday likely was to ensure he avoided any sort of health concern. When Cook sat out Weeks 6 and 17 last season, Mattison combined for 35 touches, 175 yards from scrimmage and two touchdowns.

Mattison appears fairly secure in the second spot on Minnesota's depth chart, according to Eric Smith of the team's official website.

The Vikings lost Mike Boone to the Broncos in March, before selecting Kene Nwangwu in the fourth round of the 2021 NFL Draft. Nwangwu made waves with a 4.32-second 40-yard dash at his pro day, but only after an unexciting college career in which he was limited to 150 total touches over four seasons at Iowa State. While the raw talent could eventually make him a threat, Nwangwu isn't likely to put up a serious challenge against Mattison this summer, considering the third-year pro has averaged 4.6 yards per carry and 9.0 per catch to this point in his career, with 219 touches in 26 NFL appearances. Dalvin Cook should continue to dominate backfield work, but Mattison is easily the best bet to handle whatever's left.

Mattison ran for 95 yards and a touchdown on 21 carries, corralling all three of his targets for 50 yards and a receiving TD during Sunday's 37-35 win against the Lions.

In relief of Dalvin Cook, who was absent Week 17 following the loss of his father, Mattison got out to a slow start with eight yards over his first three attempts of the afternoon. He came alive on Minnesota's fourth offensive drive, notching 25 yards on his first three touches on the possession before coasting 28 yards on a fourth-down catch-and-run to provide the first of four Viking TDs. Given that Dalvin Cook agreed to a five-year, $63 million extension with Minnesota in September, Mattison remains an elite insurance policy as he heads into his third year under contract in 2021.

Mattison (concussion) doesn't have an injury designation for Sunday's game against the Lions.

Mattison was out for Weeks 13 and 14 while he recovered from an appendectomy and then missed Week 16 while navigating the concussion protocol. He's now back for what likely will be his second start of the year, as Dalvin Cook will miss the game for personal reasons. Mattison managed just 30 total yards against Atlanta in his first start, but he does have an excellent matchup with the Lions in Week 17. Cook had 252 total yards and two TDs when the Vikings beat the Lions in Week 9.

Mattison (concussion) was a limited participant at Thursday's practice.

Mattison maintained his same level of activity from Wednesday, suggesting he didn't make any further advancements through the NFL's five-step concussion protocol. With a return to full activity Friday along with clearance from an independent neurologist, Mattison would still be able to put himself on a path to suit up for Sunday's season finale versus the Lions. If active for the contest, Mattison would likely be thrust into a lead role out of the backfield with star tailback Dalvin Cook (personal) having already been ruled out for the contest.

Mattison (concussion) was a limited practice participant Wednesday, Ben Goessling of the Minneapolis Star Tribune reports.

Mattison's return to practice coincides with news that Dalvin Cook won't be able to play Week 17 as he tends to a personal matter. Of course, Mattison will have to work his way through and clear the NFL's concussion protocol, but if he does he's slated to lead the Vikings backfield Sunday in Detroit. Aside from Mattison, Ameer Abdullah and Mike Boone are Minnesota's remaining healthy and available running backs.

Mattison (concussion) returned to practice Wednesday, putting him on track to start Sunday's game against Detroit in place of Dalvin Cook (personal), Chris Tomasson of the St. Paul Pioneer Press reports.

Between an appendectomy and now the concussion, Mattison has missed three of Minnesota's past four games. He'll have a nice chance to end the season on a high note if he's cleared from the concussion protocol, likely stepping in as the Vikings' lead back against a Lions defense that's given up the fourth-most rushing yards (135.5). The Vikings also have Ameer Abdullah and Mike Boone in the backfield, but the two have combined for only 14 carries this season.

Mattison (concussion) has been ruled out for Friday's game in New Orleans.

Mattison sat out Weeks 13 and 14 due to an appendectomy, and upon his return this past Sunday against the Bears, he emerged from the contest with a concussion, which didn't allow him to practice this week. Until he does, he'll have made negligible progress through the protocol for head injuries. While Dalvin Cook will continue to lead the backfield, there may be some RB reps available for Ameer Abdullah, Mike Boone and C.J. Ham (quadriceps).

Mattison (concussion) missed practice Wednesday.

After missing two games due to an appendectomy, Mattison logged six snaps on offense and eight more on special teams en route to two touches for 15 yards from scrimmage Week 15 against the Bears. In the course of that contest, he suffered a concussion and now is subject to the protocol for head injuries before he can suit up again. Because the Vikings are operating on a short week with a Friday matchup with the Saints on tap, Mattison seems unlikely to play Week 16, especially with no practice reps yet under his belt.

Mattison (concussion) was not spotted at the portion of Wednesday's practice open to the media, Ben Goessling of the Minneapolis Star Tribune reports.

Mattison was also listed as a non-participant in Tuesday's practice. The second-year back served as the top backup to Dalvin Cook in Week 15, but he suffered a concussion in his return to action and will now require full medical clearance before retaking the field. Ameer Abdullah and Mike Boone could be in line to backup Cook against the Saints on Christmas Day.

Mattison was listed as a non-participant in Tuesday's practice due to a concussion.

After missing two games following an emergency appendectomy, Mattison returned to action for the Week 15 loss to the Bears and played a minor role behind lead back Dalvin Cook, finishing with one carry for one yard and a 14-yard reception over his six offensive snaps. Mattison appears to have picked up a concussion along the way, and he'll now have to clear the NFL's five-step protocol for head injuries in order to suit up Christmas Day against the Saints. If Mattison can't play, Ameer Abdullah and Mike Boone would serve as the top depth options behind Cook.

Mattison (illness) is active Week 15 against the Bears.

Mattison has been sidelined back-to-back weeks, but a brief return to Thursday's session opened the door for the second-year back to be back in action Week 15. There will remain legitimate questions about his usage, however, as Dalviin Cook is the unquestioned No. 1 back, and both Ameer Abdullah and Mike Boone are active for the contest as well.

Mattison (illness) is listed as questionable for Sunday's game against the Bears.

A return to practice Thursday as a limited participant gives Mattison a shot to avoid his third straight absence. He had an appendectomy Dec. 5, after seeing just five carries and 22 snaps in a three-game stretch Weeks 10-12. The Vikings figure to give Dalvin Cook the vast majority of backfield work in a crucial game this week, regardless of Mattison's availability.

Mattison (illness) was a limited practice participant Thursday.

During the portion of the session open to the media, Mattison took part in stretching and individual drills, which was enough for him to get the limited tag on Thursday's injury report. He's missed the last two games after getting an appendectomy Dec. 5, but his presence at practice may indicate he won't make it three.

Mattison (appendectomy) went through stretches and individual drills during the open portion of Thursday's practice, Eric Smith of the Vikings' official site reports.

Mattison's appearance at practice is his first since Dec. 4, as he required an emergency appendectomy a day later. The extent of the running back's participation Thursday won't be known until the Vikings release their second Week 15 practice report later in the day, but his presence on the field at least gives him an outside chance at returning from a two-game absence Sunday against the Bears.

Mattison (illness) didn't practice Wednesday.

Mattison underwent an appendectomy Dec. 5 and has missed two games in the process. Thus, it's no surprise he's unable to practice roughly a week and a half later. While Mattison has been sidelined, fellow backs Ameer Abdullah, Mike Boone and C.J. Ham have combined for 16 touches behind clear bell cow Dalvin Cook, who accrued a whopping 62.

Mattison (appendectomy) has been ruled out for Sunday's game against Tampa Bay.

Mike Boone and Ameer Abdullah will be on hand for the tiny share of backfield work that doesn't go to Dalvin Cook, while Mattison will miss a second straight game after his Dec. 5 appendectomy.

Mattison (appendectomy) didn't practice Thursday, Andrew Krammer of the Minneapolis Star Tribune reports.

Mattison sat out the Vikings' Week 13 win over the Jaguars after undergoing appendix surgery this past Saturday. Following back-to-back missed practices Wednesday and Thursday, we'd be surprised if he ends up backing up Dalvin Cook on Sunday against the Buccaneers.

Mattison underwent a successful appendectomy Saturday and has been ruled out for Sunday's game versus the Jaguars, Tom Pelissero of NFL Network reports.

Mattison's absence could be extended beyond Week 13. Browns tight end Austin Hooper notably missed two games earlier this season after undergoing an appendectomy. A more definitive timeline should be revealed when the Vikings start practicing during the upcoming week. For Sunday's matchup against the Jaguars, Mike Boone and Ameer Abdullah figure to see more work behind lead back Dalvin Cook.

Mattison (illness) will not play in Sunday's matchup against the Lions, Ben Goessling of the Minneapolis Star Tribune reports.

Mattison has only played 22 snaps across the last three weeks, but this injury could test the Vikings' depth at running back, particularly with Dalvin Cook (ankle) a bit banged up throughout practice all week. Expect to see a little bit of Mike Boone and Ameer Abdullah in an effort to spell the Vikings bellcow in Sunday's pivotal divisional contest.

Mattison had two carries for six yards in Sunday's win over Carolina.

Mattison played 12 snaps on offense as he was used on a series when Dalvin Cook was briefly sidelined with a sore ankle. Earlier in the season, it looked like he'd get a decent number of carries to take the load off Cook. However, Cook has received nearly every touch out of the backfield the last three games.

Mattison had one carry for six yards in Sunday's loss to Dallas.

Mattison played just six snaps on offense. He's had just three carries the last two weeks, and just 18 carries the past four weeks. Earlier in the season it looked like he'd get a decent number of carries to take the load off starter Dalvin Cook. However, Cook has received nearly every touch out of the backfield the last four games.

Mattison registered four rushing yards on two carries during Monday night's 19-13 win against the Bears.

During a contest in which neither team led by more than six points at any juncture of the game, Dalvin Cook expectedly shouldered the bulk of the workload, fielding 30 of 32 running back carries and 94.4 percent of the overall RB touches on the night. An approaching Week 11 matchup against the Cowboys' 31st-ranked rush defense would provide opportunities to Mattison in a scenario where the game gets out of hand, and Cook ultimately yields second-half carries to the backup. Mattison was able to rack up 69 rushing yards on 12 attempts during a 14-point win over Detroit in Week 9.

Mattison carried the ball 12 times for 69 yards in Week 9 against Detroit.

Mattison got only two carries prior to the fourth quarter, when the Vikings were up 34-13. However, he helped to close out the game, picking up chunk gains of 14, 18 and 18 yards on the team's final possession. It's difficult to count on that type of game script on a weekly basis, meaning Mattison is trustworthy only if Dalvin Cook is forced to miss additional game action.

Mattison rushed three times for eight yards and wasn't targeted in the passing game in Sunday's 28-22 win over Green Bay.

Mattison was a non-factor as Dalvin Cook (groin) returned from injury and rumbled for 229 scrimmage yards and four touchdowns. Cook should handle a workhorse role as long as he's healthy, relegating Mattison to change-of-pace duties against the Lions in Week 9 and beyond.

Mattison registered 26 rushing yards on 10 carries, also catching one of two targets for four receiving yards during Sunday's 40-23 loss to the Falcons.

Game script worked against Mattison heavily in this one, with the Vikings falling into a 20-0 deficit by the halftime break. The 22-year-old back got out to a hot start with seven yards on his first rush attempt of the day, but his other seven first-half carries yielded a total of only 19 yards. Mattison was explosive in relief of Dalvin Cook (groin) last Sunday night against the Seahawks, gaining 136 scrimmage yards on 23 touches while posting a 5.6 yards-per-carry average. His fantasy utility may be diminished in the near future, as NFL Network's Tom Pelissero reports that Cook has an extremely strong chance to return following Minnesota's Week 7 bye.

Mattison will be the Vikings' No. 1 running back Sunday against the Falcons with Dalvin Cook (groin) sidelined for the contest, Chris Tomasson of the St. Paul Pioneer Press reports.

The Vikings made the expected move and formally ruled out Cook, who suffered an adductor strain Week 5 in Seattle. Prior to his departure in the third quarter, he had 22 touches, and he also averaged 20.5 touches through the first four games of the campaign. By the end of this past Sunday's 27-26 loss, Mattison himself racked up 23 touches for 136 yards from scrimmage, so he seems poised to handle a significant workload this weekend. As a result, he seems like a great bet to produce versus an Atlanta defense that has given up 139 yards from scrimmage per game to running backs in 2020. Mattison's opportunity may be short-lived with a Week 7 bye on tap.

Mattison is expected to serve as the Vikings' feature back in Sunday's game against the Falcons with Dalvin Cook (adductor) unlikely to be available for the contest, Chad Graff of The Athletic reports.

The Vikings haven't formally commented on Cook's status for Week 6, but with the running back undergoing an MRI on Monday that revealed an adductor strain, the expectation is that he'll be withheld from action against Atlanta before being re-evaluated following Minnesota's Week 7 bye. With Cook exiting in the second half of the Vikings' 27-26 loss to the Seahawks over the weekend, Mattison rose to the occasion, carrying 20 times for 112 yards while hauling in all three of his targets for 24 yards. Reserve backs Mike Boone and Ameer Abdullah could take on slightly larger roles Week 6 than they would normally earn when Cook is available, but Mattison demonstrated in Seattle that he could capably handle a three-down workload. With a juicy matchup on tap versus a weak Atlanta defense, Mattison looks like a strong lineup option in both PPR and non-PPR formats this week.

Mattison took over for an injured Dalvin Cook (groin) in the second half of Sunday's loss to Seattle, receiving 20 carries for 112 yards while adding three receptions for 24 yards.

Cook was briefly forced out of the contest in the third quarter with a groin injury, but he was only able to return for one more carry before leaving the game for good. That opened the door for Mattison to take over as lead back, and the 22-year-old was up to the task. Mattison was able to do his best Cook impersonation by ripping off chunk after chunk against the Seahawks' stout front seven. He even resembles Cook a bit in terms of stature and appearance, so you may not have even noticed the change if you were due for a visit with the optometrist. Cook will have an MRI done Monday, so we should get more information on whether Mattison will become a prize off the waiver wire in a potential start against Atlanta on Sunday.

Mattison registered 17 rushing yards and a touchdown on seven carries during Sunday's 31-23 win against the Texans.

Dalvin Cook momentarily exited the game with an apparent injury at the 11:27 mark of the fourth quarter, as Mattison stepped into a red-zone opportunity and delivered a four-yard TD run to provide Minnesota with a two-possession lead. Cook was able to quickly return to the contest, limiting Mattison to three more carries and six rushing yards the rest of the way. Mattison will remain the Vikings' clear No. 2 option at running back as the team transitions into a Week 5 matchup against Seattle's top-five rush defense.

Mattison had eight carries for 27 yards in Sunday's loss to Tennessee.

Mattison played on 16 of 65 snaps as he still had a decent role even on a day when Dalvin Cook had 181 yards rushing. Mattison had ten touches in Week 1 before just four touches last week, so his role off the bench will be inconsistent but he has a chance to be involved enough for value in deeper formats, even when Cook is healthy.

Mattison registered three carries for 13 yards, while also contributing one catch for three receiving yards during Sunday's 28-11 loss to the Colts.

There seemed to be a fantasy-relevant role available for Mattison based on Week 1, as he collected 80 scrimmage yards on 10 touches while fielding 37 percent of the offensive snaps against the Packers. Week 2 was certainly disappointing in comparison, as Mattison totaled only four offensive touches to Dalvin Cook's 16. The fact that Minnesota fell into a significant hole on the scoreboard mitigated Mattison's involvement, but if the Vikings can keep the score close or even take a lead Week 3 against Tennessee, the second-year back is more likely to get involved.

Mattison had six carries for 50 yards and four receptions on four targets for 30 yards in Sunday's loss to Green Bay.

Mattison's fantasy value is mostly as the backup to starter Dalvin Cook in a run-oriented offense, so it was encouraging to see him get a sizeable workload in a game where Cook was healthy. Mattison had four targets in the passing game, one off his career high, and nearly had as many snaps on offense on pass plays as Cook (14 for Cook, 12 for Mattison). Cook still had more snaps on offense overall (30 to Mattison's 19), but this game bodes well for Mattison having value in deeper formats even when Cook is healthy.

Mattison enters training camp in a backup role after Dalvin Cook decided against a holdout, the Vikings' official website reports.

Mattison was a frequent subject of fantasy hype in June and July when Dalvin Cook announced his holdout from team activities. The fourth-year pro ended up reporting for training camp, but Mattison is still one of the more valuable backups in the league, given the nature of Minnesota's offense as well as the reality that Cook has missed multiple games in each of his three NFL seasons. Of course, the Vikings also have Mike Boone and passing-down specialist Ameer Abdullah on their roster, so there's no guarantee of Mattison taking on Cook-like workloads in the event of a Cook injury.

Mattison finished the 2019 regular season with 100 carries for 462 yards and one touchdown while catching 10 passes for 82 yards in 13 games.

The 21-year-old worked as Minnesota's No. 2 running back for most of the season and performed well, but he was unfortunately sidelined for Dalvin Cook's late-season, two-game absence, losing a chance to work as the starter. Overall it was a solid rookie campaign for Mattison, but his fantasy prospects for 2020 remain limited with Cook still under contract and primed to be the feature back.

Mattison (ankle) practiced fully Wednesday.

Dalvin Cook (shoulder) also logged a full session Wednesday, which sets the stage for him to head the Vikings' backfield in Sunday's playoff opener against the Saints, while Mattison works in a change-of-pace/complementary role.

Mattison (ankle) expects to play in Sunday's game at New Orleans, Andrew Krammer of the Minneapolis Star Tribune reports.

The same goes for Dalvin Cook (shoulder), who also missed the final two games of the regular season. It sounds like both running backs will practice Wednesday, but it isn't clear if they'll be full participants or limited.

Mattison (ankle) is inactive for Sunday's game against the Bears.

While continuing to manage the ankle injury, Mattison was unable to advance beyond limited participation in practice this week. Because the Vikings are already locked in as the NFC's No. 6 seed entering Sunday, Mattison won't be asked to play through the injury with the playoffs on the horizon. Both Mattison and Dalvin Cook (shoulder) should be ready to go for the wild-card round, but Mike Boone and Ameer Abdullah will headline the Minnesota backfield in the meaningless regular-season finale.

Mattison (ankle) is listed as questionable for Sunday's game against the Bears, Courtney Cronin of ESPN.com reports.

Locked in for the NFC's No. 6 seed, the Vikings reportedly are leaning toward a cautious approach to their meaningless Week 17 contest. That would seem to favor inactive status for Mattison, but it apparently isn't a sure thing, whereas Dalvin Cook (shoulder) already has been ruled out. Should Mattison join Cook on the inactive list, Mike Boone and Ameer Abdullah would be Minnesota's only backfield options for Week 17. The team is scheduled for a 1:00 p.m. ET kickoff.

Mattison (ankle) was a limited participant in Wednesday's practice.

Both Mattison and Dalvin Cook (shoulder) had their reps capped in the Vikings' first traditional practice of the week (the team held a walk-through session Christmas Day), but neither running back is certain to be available Sunday against the Bears. With the Vikings locked into the No. 6 seed in the NFC playoffs regardless of how any Week 17 game plays out, there's reason to think the team may use caution with both banged-up backs and withhold them from action. The Vikings will provide a final update on Mattison's status for the regular-season finale shortly after Friday's practice.

Mattison (ankle) was a limited participant in Wednesday's walk-through practice.

While it's encouraging in some sense that Mattison wasn't deemed a non-participant to begin the week, the Vikings probably won't have a better feel for his status for the Week 17 matchup with the Bears until getting a look at him in more traditional practices Thursday and Friday. Given that the Vikings are locked in as the NFC's No. 6 seed in the playoffs, it wouldn't be surprising if the team acted conservatively with both Mattison and top back Dalvin Cook (chest) -- who was also limited Wednesday -- and held them out for the regular-season finale to preserve their health for the postseason.

Mattison (ankle) is inactive for Monday's game versus the Packers.

With Dalvin Cook (chest) and Mattison sidelined, the Vikings' backfield is a bit short-handed during the push for playoff positioning. In their absence, Mike Boone is expected to receive the bulk of the RB reps, while Ameer Abdullah and fullback C.J. Ham also are available for touches.

Mattison (ankle), who is listed as questionable for Monday's matchup with the Packers, is viewed as a game-time decision, Ian Rapoport of NFL Network reports.

Given that Mattison has managed just one limited practice over the past two weeks while tending to the ankle injury, the Vikings appear inclined to wait and see how the rookie checks out during a workout Monday before rendering a verdict on his status. Since Mattison's availability (or lack thereof) isn't expected to be known until a few hours before Monday's 8:15 p.m. ET kickoff, he'll be a risky option for fantasy lineups, given that his managers would likely have few alternatives to turn to in the event he's inactive for Week 16. Given that the Vikings have already secured a wild-card spot in addition to the fact that Green Bay can still take home the NFC North crown with a Week 17 win over the reeling 3-10-1 Lions, Adam Schefter of ESPN speculates that Minnesota will likely take a conservative approach with Mattison and hold him out for a second straight game. If that's the case, Mike Boone would likely headline a Week 16 Vikings backfield that will be missing Dalvin Cook (chest), who has already been rul

Mattison (ankle) is listed as questionable for Monday's game against the Packers, Adam Schefter of ESPN reports.

Dalvin Cook has been officially ruled out, and Mattison remains uncertain for Monday, which could open the door for Mike Boone to get the start in the Minnesota backfield. Mattison went through individual drills in Saturday's practice and a final decision on his status will come in the hours before kickoff.

Mattison tested his ankle out during individual drills Saturday, Chris Tomasson of the St. Paul Pioneer Press reports.

We'll have to see how the Vikings officially list Mattison's practice participation level, but his presence on the field Saturday is at least a step in the right direction following back-to-back missed sessions Thursday and Friday. We'll look for added clarity with regard to his status for Monday night's game against the Packers once the Vikings' final Week 16 injury report is released, but at this stage Mattison remains iffy for the contest, while fellow back Dalvin Cook (chest) is trending toward being out.

Mattison, who was missed another practice Friday, is still dealing with swelling and pain in his sprained ankle, Andrew Krammer of the Minneapolis Star Tribune reports.

Neither Dalvin Cook (chest) nor Mattison is looking good for Monday's game against Green Bay, potentially leaving Mike Boone as the lead runner. Cook and Mattison do have one more chance to get on the practice field this week, as the Vikings won't need to release their final injury report until Saturday afternoon/evening.

Mattison (ankle) isn't practicing Friday, Chris Tomasson of the St. Paul Pioneer Press reports.

The same is true of Dalvin Cook (chest), leaving Mike Boone and Ameer Abdullah as Minnesota's healthy running backs. The Vikings haven't announced any decisions, but the early signs point to Boone handling the lead role Monday night against the Packers. A return to practice Saturday would give Mattison (or Cook) a chance to play.

Mattison (ankle) isn't participating in Thursday's practice, Ben Goessling of the Minneapolis Star Tribune reports.

Despite sitting out the Vikings' Week 15 win over the Chargers, Mattison still is hobbled by the ankle injury he picked up during the Dec. 8 victory over the Lions. Courtney Cronin of ESPN.com notes that Mattison was at least able to work with a trainer off to the side, though he didn't do any running or jogging. Mattison will have two more days to fit in some practice activity and improve his outlook for Monday's game against the Packers, but as things currently stand, both he and lead back Dalvin Cook (shoulder) seem to be in danger of missing the divisional showdown. Mike Boone took the reps with the first-team offense Thursday and would be in line to headline the Vikings' backfield Week 16 if Cook and Mattison can't go.

Mattison (ankle) may not practice Thursday, but coach Mike Zimmer said the running back is "doing better" and has "a good chance" to play Monday against the Packers, Courtney Cronin of ESPN.com reports.

Mattison didn't practice last week due to an ankle injury that resulted in the Vikings ruling out the rookie RB on the final Week 15 injury report. Meanwhile, the team doesn't expect to have starter Dalvin Cook (shoulder) on the game-day roster Monday and potentially for the season finale as well, per ESPN.com. If Mattison does take the field Thursday, it'll be a "low key" session, according to Zimmer. In any case, Mattison could set himself on a path to the lead role if he participates Thursday and maintains or even increases his activity level in the coming days. Behind Cook and Mattison, the next players up in the Vikings' backfield are Mike Boone, fullback C.J. Ham and Ameer Abdullah.

Mattison (ankle) has been ruled out for Sunday's game against the Chargers.

Unable to practice in any capacity this week, Mattison will be inactive for the first time in his young career. Ameer Abdullah and/or Mike Boone will handle backup work, with Dalvin Cook potentially getting even more touches than usual if the Vikings end up in a tight contest.

Mattison (ankle) isn't practicing Friday, Chris Tomasson of the St. Paul Pioneer Press reports.

Mattison told the media he'd be fine for Sunday's game against the Chargers, but a third consecutive missed practice suggests otherwise. It remains to be seen how the Vikings list the rookie running back on their final Week 15 injury report.

Mattison (ankle) did not participate in Thursday's practice.

Mattison said Wednesday that he'll play in Sunday's game against the Chargers, but back-to-back absences from practice cast doubt on his assertion. Should the rookie ultimately land on the Week 15 inactive list, Dalvin Cook might see even more work than usual during Sunday's game against the Chargers. Alternatively, the Vikings could give Mattison's vacated snaps to reserve running backs Ameer Abdullah and Mike Boone.

Mattison (ankle) was a non-participant in Wednesday's practice.

Mattison appears to have picked up an ankle injury during Week 14's win over the Lions, during which he logged 14 carries for 46 yards and hauled in both his targets for 18 yards. Despite being held out of practice to begin the week, the rookie running back told Chris Tomasson of the St. Paul Pioneer Press on Wednesday that he fully expects to suit up against the Chargers on Sunday and is taking his recovery "day by day." Mattison will have two more chances to up his level of activity in practice ahead of Week 15's tilt in Los Angeles.
