Carter reverted to the Cardinals' practice squad Monday.
Carter made his season debut in Sunday's 36-30 overtime loss to Carolina and ended the contest as Arizona's lead runner after James Conner suffered a knee injury. Overall, Carter played 25 of 70 offensive snaps in the game, recording five carries for 18 yards and a team-high five catches (on five targets) for 30 yards. DeeJay Dallas also got in the act with a one-yard touchdown reception on 16 plays. The Cardinals haven't been a definitive update on Conner's health, but with Emari Demercado (back) on injured reserve and Trey Benson (ankle) having sat out the Week 16 game, Carter could be a regular out of the Cardinals backfield this coming Sunday versus the Rams.
