Miles Austin's chances don't look good

IRVING, Texas -- The chances of Dallas Cowboys wide receiver Miles Austin playing Sunday against the San Diego Chargers seem slim after he missed his third day of practice because of a hamstring strain.

Coach Jason Garrett does not have a hard-and-fast rule about a player having to practice in order to play, but Austin’s history of hamstring trouble will play a factor in the decision. Austin has been bothered by hamstring strains the last two seasons, but did not miss a game last year after missing six games in 2011.

"If anything because of the last two years, we’ll be conservative with that decision at game time," owner and general manager Jerry Jones said on KRLD-FM.

Wide receiver Dwayne Harris returned to practice after missing Wednesday and Thursday with a bruised hip. If Harris can play it is possible he would give up the punt and kick return duties. Cole Beasley handled the punt chores after Harris was hurt last week against the St. Louis Rams and Lance Dunbar could take over on kickoffs.

DeMarcus Ware was at practice again but did not appear to be in shells. He was limited on Wednesday and Thursday because of a stinger. Linebacker Ernie Sims will be available after missing two games with a groin injury.
