"The Dallas Cowboys could be without two starters for Sunday's home game against the Washington Redskins.

Wide receiver Roy Williams is questionable with a groin injury suffered this week in practice, and it doesn't look like he'll play.

Running back Marion Barber, who has missed the last two games with a calf injury, was limited in practice this week and isn't expected to participate against Washington. Felix Jones will start in place of Barber."
