CLEVELAND -- Cowboys running back Marion Barber has gone to the locker room with bruised ribs, and his status is "unknown," according to the club's P.R. department.

Rookies Felix Jones and Tashard Choice will probably take it the rest of the way. Werder and I will check in with Barber after the game.
