While the Cowboys claim quarterback Tony Romo's status for Sunday's game against the Eagles hasn't been determined yet, it is believed that Romo will not be able to play.
The Cowboys will reportedly sign Jon Kitna as insurance at the quarterback position, according to the Fort Worth Star Telegram.
Romo and Kyle Orton were the only quarterbacks on the Cowboys roster.
The 41-year-old Kitna played in 141 games over 15 seasons in the NFL, but hasn't been in the league since 2011. He spent his last three seasons (2009-11) with the Cowboys, appearing in 13 games. Kitna started nine games in 2010 for the Cowboys after Romo was lost due to injury.
Kitna started 124 games in his career, passing for 29,745 yards, 169 touchdowns and 165 interceptions. His record as a starter is 50-74.
The Cowboys have not announced a move to make room for Kitna on the active roster yet.
