Dalvin Cook is officially playing against the Steelers tonight. He'll be out there in a shoulder harne s and is expected to see his regular workload, according to ESPN's Adam Schefter.Indications on Thursday morning were that and things was trending in that direction, pending medical clearance. Now it appears he has gotten that clearance and is good to go for Thursday Night Football.The Vikings' superstar running back suffered a dislocated left shoulder and a torn labrum against the 49ers just Matt Harvey Jersey 11 days ago (though Mike Zimmer oddly later disputed the reports that Cook had torn his labrum). Players from both teams came onto the field and took a knee as a tearful Cook was carted off the field with what appeared to be a significant Darryl Strawberry Jersey injury.It turned out to not be as serious as it looked in the moment, and initial expectations after testing were that Cook would mi s two games and return on Monday night against the Bears in Week 15.But apparently the Vikings don't feel like there's much risk of reinjury or aggravation, as they've given him the green light to play after mi sing just one game. It might just be a pain tolerance i sue for Cook, who is a notoriously hard-working competitor. His rehab over the past week-and-a-half and it allowed him to quickly regain his strength and range of motion. He clearly didn't want to mi s this must-win game for the Vikings.This will be interesting. As Schefter mentioned, Cook has worn a shoulder harne s before and played well in that playoff victory Wilmer Flores Jersey over the Saints. His lower body is still 100 percent, which is the most important thing for a running back.Scroll to ContinueBut will this affect his ability to catch the football or his willingne s to receive and deliver contact? What happens if he takes a big blow to the shoulder? Defenders are going to be well aware of the injury he's playing through. Keep in mind that there are four games remaining after Asdrubal Cabrera Jersey this one and that Cook is under contract for four more seasons with an average cap hit of $13.8 million.If Cook is to see his normal workload tonight, that could be upwards of 30 touches. We'll just have to see how his body holds up.Alexander Mattison, who has exceeded 100 yards from scrimmage in all three of his starts this season, goes back to backup duties but may Tim Tebow Jersey see slightly more touches than usual to spell Cook. Kene Nwangwu presumably returns to being a kick returner only.The Steelers have given up 829 rushing yards over the past five weeks, which is the most among all teams over that time frame.Kickoff is at 7:20 p.m. central time on FOX and NFL Network.
