Why isnt Marion Barber playing?

do you people ever think ahead? i'm sure he has enough strength to play this game but if he were to play this week, he would irritate the toe even more and it would become injured worse. if it gets worse he would miss the next few games which we may really need him to help us win. you guys can make fun of romo all you want but the broken pinky affected his throwing style and besides, look at what happened to brady quinn.
