Cowboys sign QB Jon Kitna to backup Kyle Orton against Eagles

The Cowboys roster is getting a bit older in response to Tony Romo's herniated disk. Dallas has signed 41-year-old Jon Kitna to backup likely starter Kyle Orton on Sunday against the Eagles, according to Clarence Hill Jr. of the Fort Worth Star-Telegram.

The somewhat bizarre move comes after the Cowboys tried to workout veteran David Carr and journeyman John Skelton. Carr had been stuck at an unknown airport due to flight delays, according to NFL Media's Ian Rapoport. Skelton, Caleb Hanie and Tyler Thigpen were all set to work out for Cowboys officials, but were sent home by the organization, according to Rapoport.

Kitna has not appeared in a game since 2011 and has not started a game since Christmas of 2010. The veteran had a 15-year career in NFL prior to his one-season hiatus and has played for the Seahawks, Bengals, Lions and Cowboys. Kitna was serving as a math teacher and football coach at his high school alma mater prior to the Cowboys signing, according to the Seattle Times.

The Cowboys have still not officially ruled out Romo for Sunday's game, but this just another sign that Orton is likely to get the call.
