The Arizona Cardinals have signed running back Thomas Clayton, if anything to give them a body to practice with in training camp.

Running back's Beanie Wells, Ryan Williams, and Javarris James are all struggling with injuries. Wells is expected back in time for the preseason games as he recovers from surgery last year. Williams is still recuperating from a torn patella tendon he suffered in a preseason game last year, and James isn't at full health after injuring an abductor muscle.

Clayton played with the Cleveland Browns last year and was signed quickly because the team was short running backs for a practice game on Sunday.
