It’s “safe to assume” that tailback Dalvin Cook (shoulder) won’t practice today, Kevin O’Connell said.

Cook is still considered day to day for Sunday, the tweet went on to say. It added they’ll try to get him some work at least in walk-throughs this week before making a decision on whether he will play vs. Saints. Mattison would get the start and be a potential RB1 candidate against the Saints in a game that will be played in London.

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.

Vikings RB Dalvin Cook is out for the rest of Sunday's game against the Lions with a shoulder injury.

Cook was having a strong day, rushing for 96 yards and a touchdown on 17 carries but now the question is how serious is the shoulder injury. Alexander Mattison is now in at running back with the Vikings trailing the Lions.

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.

Vikings RB Dalvin Cook has been removed from the reserve/COVID-19 list.

As long as his conditioning is good, fire up Cook Week 17.

Minnesota Vikings running back Dalvin Cook has been placed on the reserve/COVID list.

This is a massive blow for the Minnesota Vikings as they try to jockey their way to a postseason berth. Cook has been ruled out, so fantasy managers are set to be down an RB1 for the semi-finals, so here is hoping you found a way to handcuff Cook with Alexander Mattison this year. Mattison, who was activated from the list yesterday, has a tough matchup against the Los Angeles Rams but has volume-based RB1 appeal. Mattison is currently our third-ranked running back for Week 16.

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.

Minnesota Vikings running back Dalvin Cook is active for Thursday Night Football against the Pittsburgh Steelers.

Cook missed Week 13 with a shoulder injury with what was expected to be a multi-week absence. He was able to practice on a limited basis on Tuesday and Wednesday and has been cleared to play tonight against the Steelers. Cook could be on a pitch count but is still our 12th ranked running back for Week 14.

Minnesota Vikings running back Dalvin Cook is expected to play tonight against the Pittsburgh Steelers

Cook was expected to be sidelined until Week 15 but has made a rapid recovery. Cook appears to have healed enough to play and is awaiting final clearance from the team's medical staff ahead of tonight's contest. Alexander Mattison will go back to a reserve role but could see a larger workload than normal if the team chooses to limit Cook's snaps. This is a situation to monitor as it will affect the fantasy value of Mattison as well as Cook for Week 14.

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.
