The Dallas Cowboys have signed Jon Kitna as their third-string quarterback, according to Ian Rapoport of NFL.com.
The Cowboys tried out several quarterbacks on Tuesday, including Tyler Thigpen, Caleb Hanie and John Skelton, but in the end decided to go with Kitna, who had served as the team's backup QB from 2009-'11, and started nine games for the team in 2010 when Tony Romo was sidelined with a broken clavicle.
