Cowboys owner Jerry Jones expects running back Marion Barber to play on Sunday. Dallas will travel to Denver to face the Broncos this weekend. Barber missed Monday night's game against the Panthers with a strained left quad. "[Barber] did more [Wednesday] than we thought and he will have expectations, I would like to reserve that to after practice, but I bet he's pretty aggressive out here in practice, listening to how he responded [Wednesday] and listening to these trainers," Jones said.
