Betts out for the game

ARLINGTON, Texas -- Redskins running back Ladell Betts is out for the game with a knee injury. It apparently happened on a 2-yard run off right tackle with just over six minutes left in the first quarter. Bradie James made the tackle and Betts' foot seemed to get caught up in the turf.

Obviously, it's serious enough that the Redskins immediately ruled out his return for this game. Betts had a big day against the Broncos last Sunday. He'll be replaced in the lineup by Rock Cartwright. We might also see Quinton Ganther get some carries.

Another huge setback for the Skins.
