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

EDGE Analysis

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 will be left with Ty Chandler, Kene Nwangwu and practice-squad members Myles Gaskin and DeWayne McBride in the backfield if Mattison is unable to play Week 11 against the Broncos.

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

EDGE Analysis

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.

EDGE Analysis

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.

EDGE Analysis

Mattison led the backfield with 18 touches 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.

EDGE Analysis

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.

EDGE Analysis

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.

EDGE Analysis

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.

EDGE Analysis

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, and 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.

EDGE Analysis

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 finished with 51 yards on seven touches in his team debut Sunday.

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.

EDGE Analysis

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.
