Dallas Cowboys receiver Miles Austin is on the verge of missing a second straight game because of a hamstring injury.
Austin was listed as doubtful Friday after not participating in practice all week leading into Sunday's game against Denver.
Linebacker Justin Durant and backup defensive end Edgar Jones were listed as doubtful with groin injuries. Durant was out of practice all week, and Jones sat out the final two days after limited participation on Wednesday.
Hamstring problems have slowed Austin throughout his career. He made it through all of training camp and the first two games healthy before injuring the hamstring against St. Louis.
Receiver Dwayne Harris (hip) and defensive end George Selvie (concussion) are questionable against the Broncos.
