No Miles Austin at practice

IRVING, Texas -- Cowboys wide receiver Miles Austin missed Wednesday's practice with a hamstring injury.

Austin, who missed Sunday's game at San Diego with the same injury, is getting better, according to coach Jason Garrett. But Austin's absence raises questions about his availability for this Sunday's clash against undefeated Denver.

"Miles is a good player and he's off to a really good start," Garrett said. "He's been as healthy as he's been the last couple of years, up until hurting the hamstring and being out last week. He's made a lot of plays for us, underneath plays, a couple of plays down the field -- he's certainly a good player. He starts and he has a big role on our team for a reason."

Linebacker Justin Durant (groin) and defensive end George Selvie (concussion) also missed practice.

Defensive end DeMarcus Ware, who tweaked his back in the Chargers game and is dealing with a neck issue, was in full pads during Wednesday's practice.
