Head coach Kevin O'Connell says that Dalvin Cook is day-to-day after leaving Week 3 with a shoulder injury.

Mattison has proved over and over again that he is a legitimate fantasy asset when Cook is forced to miss games, including his 44-yard, two-touchdown performance in Week 3. He currently stands as the RB20 (before MNF) on the week, despite only logging 39% of the offensive snaps.

After the team announced starting tight end Irv Smith Jr. would miss the preseason with a thumb injury, starting running back Dalvin Cook left the practice field with what appeared to be a hand injury. He returned for one team snap and then sat out the rest of Tuesday's practice at TCO Performance Center.

Later, his backup, Alexander Mattison, also appeared to injure a finger on a play. He, too, watched the rest of practice from the sideline.

And a third running back, Kene Nwangwu, suffered what coach Kevin O'Connell called a "soft-tissue, lower-leg injury" on Monday. Nwangwu sat out Monday and Tuesday.

There wasn't any other information but hopefully the injuries aren't serious. Cook, of course, is ranked high among running backs in terms of fantasy value, and we have him sixth on our running back list.

Viking put RB Alexander Mattison and WR Dan Chisena on COVID-19 reserve list, guard Kyle Hinton on practice squad COVID-19 list and LB Ryan Connelly goes to IR.

The Viking claimed RB Gallman off waivers in another move. Gallman likely at least slides in behind Cook and Nwangwu. Cook was dominant last week coming back from a shoulder injury but has dealt with his share of injuries this year and in his career, so his handcuff any given week is always worth noting.

Vikings WR Adam Thielen (ankle) will not play Week 14 against the Pittsburgh Steelers. RB Dalvin Cook (shoulder) is questionable.

The short week was going to keep Thielen out. While Obsorn is expected to start in Thielen's place, do not be surprised if Tyler Conklin gets more run.

Vikings WR Adam Thielen didn't practice on Tuesday while RB Dalvin Cook was limited.

Cook, of course, is dealing with a shoulder injury. He was listed as DNP Monday so this is a potential trend in the right direction for Thursday's game with Pittsburgh, but owners probably shouldn't get hopes up just yet. If Cook can't go, it would mean an RB1-type workload for Mattison. Meanwhile, Thielen didn't practice for the second-straight day meaning his status continues to not look good on the short week as he's dealing with his ankle injury. Reports say he's not expected to play, so it should be another big day for Justin Jefferson with Conklin and Osborn also getting more looks.

Minnesota’s Monday injury report was an estimate, but running back Dalvin Cook is again listed as a non-participant with his shoulder injury. Cook’s shoulder issue kept him out of Sunday’s game.

And after suffering an ankle injury early in Sunday’s contest, receiver Adam Thielen wouldn’t have practiced either.

The Vikings host the Steelers in a key game for both teams on Thursday night. Mattison will get the start at RB if Cook can't play while Justin Jefferson had a huge day in Week 13 when Thielen left the game.

Vikings RB Dalvin Cook (shoulder) has officially been ruled out for Week 13 at Detroit.

Cook was expected to miss this week, so no surprise here.

The Vikings play on Sunday in Detroit, and return home for a Thursday game against the Steelers four days later. Given the timing of Dalvin Cook's injury, he could miss both games before the Vikings travel to Chicago for a Monday night game on Dec. 20.

Reports have been all over the place today, but the Star Tribune speculates Cook could miss the next two games because of the timing of a short week in Week 14. The story says Cook dislocated his left shoulder on a third-quarter fumble during Sunday's loss to the 49ers and that Cook tore the labrum in his left shoulder, as first reported by NFL Network. We also reported today that HC Mike Zimmer said Cook doesn't have a labrum tear and is day-to-day. "That's what they're telling me," Zimmer said as far as the day-to-day status. While the team isn't saying much, those who cover the Vikings seem to be on the same page also appear to agree Cook is going to miss some time.

Vikings coach Mike Zimmer calls RB Dalvin Cook "day-to-day" with a shoulder injury. Says he doesn't have a torn labrum, which had been reported. Wouldn't say if he dislocated his shoulder or not. Won't rule him out yet for Sunday vs. Detroit.

There was a lot of news on Cook today. Ian Rapoport was among those to report Cook dislocated his shoulder and caused a torn labrum in Week 12 against the 49ers. He also reported Cook has been playing with a torn labrum in his other shoulder. While much of what Zimmer said was evasive, one thing to note that he did say was Cook doesn't have a torn labrum. We'll continue to update Cook's status, but in the meantime, pick up Mattison if he's on your wire.

Vikings RB Dalvin Cook tore his labrum while dislocating his shoulder yesterday, sources said the MRI revealed.

Rapoport reported earlier that Cook was already playing with a torn labrum in his other shoulder. The good news, according to the tweet, is the ailment is not season-ending. The hope is this is like 2019, when the team rests Cook a few games to have him healthy for a playoff run. If that's the case, Mattison will take over as the team's RB1 for any games Cook misses. If he's somehow made it back to your waiver wire, Mattison is a must-add.
