Things are getting worse in Dallas for the Cowboys.

First, after suffering a sprained neck, Cowboys linebacker Sean Lee has been ruled out of this weekend's big game against the Eagles.  ESPN's Adam Schefter reports Lee's neck injury is "more significant than the team thought."

Lee was previously reported as "doubtful" for Week 17 against the Eagles, but Schefter reports he "will not play Sunday."

Today, Tony Romo did not practice and is still not expected to be able to play on Sunday night.  Romo reportedly received an epidural injection Tuesday and is just going to rest leading up to Sunday's winner-takes-the-NFC-East matchup with the Eagles.

The Cowboys have not ruled Romo out of Sunday's game, but sources told ESPN's Adam Schefter and Chris Mortensen that Romo will not play and needs surgery to repair a herniated disk.

The Cowboys signed QB Jon Kitna to add depth at the position over guys like David Carr, Tyler Thigpen, Caleb Hanie and John Skelton.

"When you looked at the landscape of guys who could help on short notice, Kitna was a guy who kind of rose to the top of that," Cowboys head coach Jason Garrett said. "We have a great history with him. He's been a heckuva football player in this league for a long time. He started a lot of games for us, knows this offense, knows this environment. We felt like on short notice he gives us the best chance if he did in fact have to play in this ballgame."
