Chase Edmonds is going to get a month to rehab his injured ankle.

The Cardinals put their starting running back on injured reserve Saturday, meaning they can start the clock on his ability to return from IR with Sunday's game against the Panthers. A player must sit out at least three games before being able to return from IR. In Edmonds' case, that would span the bye -- meaning the first game for which he would be eligible to return would be the Monday night home game against the Rams Dec. 13.

To replace Edmonds, the Cardinals promoted running back Tavien Feaster from the practice squad to the 53-man roster.

The Cardinals also have their long snapper for the game, making Beau Brinkley on of their two practice-squad elevations for the week. Wide receiver Greg Dortch was the other practice squad call-up for the game.

On the season, Edmonds has 430 yards rushing on 76 carries for an average of 5.7 yards a carry (his career-high for yards in a season is 448), with another 30 receptions for 211 yards. James Conner is expected to get the bulk of the work, with Eno Benjamin getting his first extended offensive work of his career.

Benjamin scored his first NFL touchdown last week against the 49ers after Edmonds went out with the injury on the game's first play, while Conner had three touchdowns and 173 total yards rushing and receiving getting the vast majority of the offensive snaps.

The Cardinals aren't the only ones dealing with injuries this week. Starting Rams wide receiver Robert Woods tore his ACL in practice Friday, ending his season and turning the acquisition of Odell Beckham Jr. from a talent boost to a needed filling of a hole in the offense.
