IRVING, Texas -- Starting running back DeMarco Murray and backup Felix Jones were limited in practice Thursday, according to the Cowboys injury report.

Jones missed practice Wednesday with a knee problem but returned in a limited fashion Thursday. Murray has missed the last six games with a sprained foot.

Coach Jason Garrett hasn't said if either player will play Sunday night against Philadelphia, but it's expected one of them, if not both, will.

Wide receiver Miles Austin (hip), center Ryan Cook (knee), defensive end Sean Lissemore (ankle) and left tackle Tyron Smith (ankle) were limited in Thursday's practice.

Offensive line coach Bill Callahan said he is optimistic Cook and Smith will play Sunday.

Austin has battled hamstring problems this season, and he suffered a hip injury in the Thanksgiving Day game against Washington.

"I think it’s not easy to go 16 games without being banged up," quarterback Tony Romo said. "I can promise you there’s a lot of guys who have played through a lot of stuff. And Miles is, having hurt himself last week. He’s got to play through a little bit of pain, and that’s part of his greatness, is his ability to come out and still play at a good level. I’m excited. Hopefully he’ll be able to play this week."

Safety Charlie Peprah was a new addition to the injury report with a foot injury. He did not practice.

Also, defensive lineman Ben Bass (left ankle sprain), center Phil Costa (ankle), nose tackle Jay Ratliff (groin) and cornerback Orlando Scandrick (hand and wrist) did not practice.

It might take six-to-eight weeks for Scandrick's hand to fully heal, but he could return sooner, though he isn't scheduled to see a doctor until next week to determine when he can play again.

Defensive end Jason Hatcher (concussion), safety Danny McCray (hip), wide receiver Kevin Ogletree (concussion) and fullback Lawrence Vickers (knee) were full participants in practice.
