TEMPE, Ariz. (AP) Arizona Cardinals running back Andre Ellington has a sprained right knee, an injury that's less serious than initially feared, and coach Bruce Arians isn't ruling him out for Sunday's game at Chicago.
Ellington suffered a mild sprain of his right posterior cruciate ligament in Arizona's 31-19 season-opening win over New Orleans.
Such injuries usually sideline a player one to three weeks, but Arians thinks Ellington might play against the Bears.
If Ellington can't go, Chris Johnson would move into the starting role with rookie David Johnson as his backup.
Carson Palmer's 55-yard touchdown pass play to David Johnson sealed Sunday's victory.
