An update on Cowboys' NT Ratliff

Posted by ESPN.com's Matt Mosley

Cowboys coach Wade Phillips said Friday that Pro Bowl nose tackle Jay Ratliff injured his right knee during Thursday's practice and is listed as questionable for Sunday's game against the Seahawks. Ratliff didn't practice Friday while undergoing treatments on his knee.

But a team source told me earlier this afternoon that he'd be "shocked" if Ratliff wasn't on the field Sunday. Phillips wasn't quite as strong with his prognosis.

"There is slight swelling," Phillips said. "We did an MRI. We think it's something that will get better. How quickly is the question."

Other than outside linebacker DeMarcus Ware, I think Ratliff is the Cowboys' most important defender. He's a high-energy player who has five tackles behind the line of scrimmage and 10 quarterback pressures. During the Bill Parcells era, a player not practicing on Friday almost certainly meant he'd miss the game Sunday. The only exception I can recall is Vinny Testaverde replacing Drew Henson on Thanksgiving. But Phillips has been more willing to rest players Friday and then allow them to play two days later.
