As the week progressed, confidence that Minnesota Vikings running back Dalvin Cook would play in Sunday's home game against the Seattle Seahawks after suffering a sprained ankle against the Arizona Cardinals decreased.
And on Sunday, Cook was officially inactive for the game.
Cook, who was listed as questionable, missed practice all week because of the injury. He was getting hours of treatment throughout the day on Saturday in an attempt to make it back, but it had been considered "unlikely" he would play, a source told ESPN's Adam Schefter.
Cook was injured with 9:52 remaining in the fourth quarter of last Sunday's 34-33 loss to the Cardinals when he was tackled low by defensive end J.J. Watt. He was momentarily replaced by backup running back Alexander Mattison but returned for the Vikings' final two series.
Cook finished with 131 yards on 22 carries.
Sunday will mark the first game with fans at U.S. Bank Stadium in 636 days.
