On Thursday morning, the Eagles announced that quarterback Michael Vick has not yet passed his ImPACT test and would not practice due to his concussion. Running back LeSean McCoy has also not yet returned to action after suffering a concussion in Week 11 against the Redskins.

Defensive tackle Fletcher Cox did not practice because of his tailbone injury, but he was not with the team on Thursday. He was excused due to a death in the family. Cox said on Wednesday that he hoped to practice by the end of the week with the intent to play Sunday in Dallas.

Running back Chris Polk did not practice with his toe sprain. Center Dallas Reynolds also missed practice with an ankle injury. Evan Mathis is preparing to start if Reynolds can't play. Danny Watkins will start at left guard if Mathis moves to center.

Offensive tackle King Dunlap improved from a limited participant on Wednesday to a full participant on Thursday with a knee sprain. Wide receivers Jason Avant (hamstring) and Riley Cooper (knee) and fullback Stanley Havili (ankle) were also full participants.

For the Dallas Cowboys, running back DeMarco Murray remains on track to make his return to the lineup as he was limited in Thursday's practice. The starting tailback has missed the past six games with a foot sprain. Felix Jones, who has started in Murray's absence, returned to practice on Thursday, but was limited with a knee injury.

Nose tackle Jay Ratliff missed practice again with a groin injury. Cornerback Orlando Scandrick also missed practice with a hand injury. The slot cornerback is not expected to play. Safety Charlie Peprah was added to the injury report Thursday after he missed the workout with a foot injury.
