Miles Austin continues to rehab hamstring

IRVING, Texas -- Dallas Cowboys wide receiver Miles Austin continued to rehab his injured hamstring during Friday's practice, making his availability for Sunday's game against the Denver Broncos doubtful.

Austin hasn't practiced since injuring the hamstring against the St. Louis Rams in Week 3.

If Austin doesn't play, Terrance Williams will take over his spot.

There was some good news along the injury front as defensive end George Selvie was cleared to practice after missing the past two days because of a concussion. Selvie might do some individual drills during Friday's practice as a precaution.

Linebacker Justin Durant (groin) and defensive end Edgar Jones (groin) missed practice. Durant might play given coach Jason Garrett's mantra that veterans can play in games if they don't practice.

Durant said Thursday his health was improving but was being cautious so there would be no setbacks.
