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

EDGE Analysis

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

EDGE Analysis

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.

EDGE Analysis

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.

EDGE Analysis

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 is 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.

EDGE Analysis

Mattison didn't practice last week due to an ankle injury that resulted in the Vikings ruling out the rookie RB on their 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.

EDGE Analysis

Unable to practice in any capacity this week, Mattison will be inactive for the first time in his young career. Mike Boone and/or Ameer Abdullah 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.

EDGE Analysis

Mattison told the media he would 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, which will be issued later Friday.

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

EDGE Analysis

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.

EDGE Analysis

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.

Mattison carried the ball 14 times for 46 yards in the team's Week 14 win over the Lions. He added two receptions for 42 yards.

EDGE Analysis

Mattison matched a season high with 14 carries, though he was still out-touched by Dalvin Cook. He wasn't particularly efficient with his opportunity, as half of his carries went for two yards or fewer. While the health of Cook was a question entering the game, Mattison's workload was seemingly due more to the Vikings' relative comfort in winning the contest, as Cook accounted for 13 of the team's 19 carries in the first half while Mattison received nine of the team's 20 carries after halftime. Mattison may be the most valuable handcuff at this point in the season, though his standalone value is questionable unless Cook suffers a setback prior the team's Week 15 contest against the Chargers.
