The Arizona Cardinals' already embattled running game has taken a severe blow with the announcement that running back Ryan Williams is out for the season with a left shoulder injury that will require surgery.
The Cardinals already are without Beanie Wells until at least Thanksgiving weekend because of a severe turf toe injury.
The hard-luck Williams missed all of his rookie season a year ago with a torn patella tendon. He injured his shoulder on a hard hit during last Thursday night's loss at St. Louis.
The injury leaves Arizona with running backs LaRod Stephens-Howling, William Powell and Alfonso Smith. Stephens-Howling missed the last two weeks with a hip flexor.
