The Cardinals have placed RB Chase Edmonds on IR for his high-ankle sprain. We already knew he'd miss this week and was expected to miss multiple games. He's still reportedly expected to return, but it's not yet clear whether Arizona expects to get him back after the mandatory 3-game absence. James Conner takes over the backfield in Edmonds' absence, with Eno Benjamin behind him.
Update: The Cardinals are also adding RB Tavien Feaster to the roster, with Edmonds out.
