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.

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.

Cook will get an MRI on his recently injured shoulder to see what kind of damage, if any, the dislocated shoulder caused. Rapoport said he's been playing with a torn labrum on the other side. But dislocated shoulders can often cause damage to the labrum, according to the video, so he could be dealing with issues to both shoulders at this point. Mattison is a must-own as a handcuff for Cook and will get a bulk of the time if Cook is out again.

Cook had his workload limited Week 4 and could be in a similar situation Week 5 against the lowly Lions defense.

Vikings RB told reporters Wednesday that he is still trying to shake his ankle injury. "I'm not 100 percent yet. I'm still working to get back to wear to need to be back at."

Injury news from the source is as locked-in as it gets. Alexander Mattison will be in play with Cook not healthy enough for a full workload.

Running back Dalvin Cook eventually made an early exit in the Vikings' 34-33 loss to the Cardinals due to a sprained right ankle suffered when Cardinals defensive lineman J.J. Watt tackled him low in the fourth quarter.

"He just got a little ankle sprain," coach Mike Zimmer said.

The story went on to say: Cook, who finished with 148 yards from scrimmage, popped up and walked gingerly toward the sideline before dropping to the turf. Vikings trainers helped him to the sideline, where his right ankle was taped up. Cook returned, taking two more handoffs, but his movements were labored, and he was eventually replaced by Mattison on the final drive. It sounds like Cook has a chance to be OK as we head into Week 3. Mattison is worth picking up as a handcuff, however, if he's still on your wire.

Vikings running back Alexander Mattison is practicing Wednesday after going through concussion protocol last week.

Dalvin Cook is set to miss Week 17 following the death of his father, so this news sets Mattison up to start in a great matchup against the Lions' terrible defense. Mike Boone and Ameer Abudallah will probably mix in in some capacity, but Mattison will be an interesting DFS play given his projected workload and the soft matchup.

Minnesota Vikings running back Alexander Mattison has been ruled out for Week 16 against the New Orleans Saints.

Mattison had been sidelined for three weeks after undergoing an appendectomy and returned in Week 15 only to suffer a concussion after only six snaps. He will miss Week 16, leaving Ameer Abdullah and Mike Boone to pick up the scraps behind workhorse Dalvin Cook. Cook is our fifth ranked running back for finals week.
