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.

EDGE Analysis

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.

EDGE Analysis

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 total yards 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.

EDGE Analysis

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.

EDGE Analysis

Cook was briefly forced out of the contest in the third quarter with a groin injury, and he was able to return for only 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. Cook will have an MRI on Monday, so we should get more information soon on whether Mattison will become a prize off the waiver wire for 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.

EDGE Analysis

Dalvin Cook momentarily exited the game with an apparent injury at the 11:27 mark of the fourth quarter, and 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 31-30 loss to Tennessee.

EDGE Analysis

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 10 touches 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.

EDGE Analysis

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; 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.

EDGE Analysis

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.

EDGE Analysis

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.

EDGE Analysis

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.
