DeMarco Murray's return in doubt again

IRVING, Texas -- Cowboys running back DeMarco Murray didn't practice on Thursday and baring a sudden change of events, he won't play in Sunday night's game at Atlanta.

Murray has missed the last two games with a sprained foot and while he's out of a walking boot, and wearing some old school adidas sneakers, he's still not ready to play in a game.

"We just got to take him week-to-week," Cowboys executive vice president Stephen Jones said. "At the end of the day he plays a tough position (and) for that injury he’s got to be 100 percent before we can put him out there and I don’t think it does anybody any good if we put him out there too early."

The running back position has some issues with Felix Jones playing with a bruised knee so it leaves Phillip Tanner and Lance Dunbar as the healthy running backs on the roster.

"I'm concerned because he’s not healthy," Stephen Jones said of Felix Jones. "We got one already (Murray) that can't play, and he's banged up. I give Felix a lot of credit, there’s other backs that probably just say, 'Hey, I need to get well before I get out there.' But Felix is tough and he wants to be out there and we know he’s not 100 percent but he wants to play."
