PHILADELPHIA -

Some Cowboys fans could be rejoicing over the news that Tony Romo could be out for the season, as bad as that may sound.

Others, might be sweating bullets.

The Eagles are staying calm and focused, preparing for either Romo or backup Kyle Orton.

Preparations to face the Cowboy offense hasn't really changed.

Romo may have better mobility than Orton, but Eagles defensive coordinator Bill Davis says both quarterbacks aren't different enough to change preparation.

His defense is playing very well coming off the Chicago game is ready to take on anyone who comes out of the tunnel Sunday in Dallas.
