The Cowboys expect to play Sunday's game without running back DeMarco Murray, and although Felix Jones is practicing today, he is limited by his bruised knee.
Executive vice president Stephen Jones said Felix Jones is playing through the injury but isn't 100 percent.
"I'm concerned, because he’s not healthy," Stephen Jones said Thursday. "We got one already that can't play, and he's banged up. I give Felix a lot of credit. There are 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.
"We’ve had players in the past that wouldn’t go out like that."
Murray has missed the past two games with a sprained foot.
The Cowboys struggled to run the ball against the Giants, who were committed to stopping the run. They had 19 yards on 17 carries. They gained 85 yards on 31 carries the previous week against the Panthers. Felix Jones sat out the last two drives of the Panthers' game after bruising his knee. He played against the Giants, though he was hurting. He had 19 yards and a touchdown on 13 carries.
Second-year back Phillip Tanner and rookie Lance Dunbar are the team's only healthy backs. They have combined for 148 yards and a touchdown on 47 career carries.
