With Tony Romo unlikely to suit up again this season, the Dallas Cowboys are on the lookout for quarterback insurance behind backup Kyle Orton.
A source informed of the team's plans told NFL Media Insider Ian Rapoport on Monday that free agents David Carr, John Skelton and Tyler Thigpen will work out for the Cowboys.
One potential problem for the Cowboys: The players are flying on Christmas Eve, Rapoport added.
A veteran of 11 NFL seasons, Carr has been unsigned since the Giants released him in late August.
Skelton was drafted by the Cardinals in 2010, and he started in 17 games for Arizona from 2010 to 2012.
Thigpen was last on an NFL roster in 2012 with the Bills. He hasn't started a game since 2010 with the Dolphins.
The Cowboys had been carrying developmental project Alex Tanney on their practice squad until the Browns pilfered him nearly a month ago.
If a veteran quarterback is signed, he will only see action in the event of an injury to Orton.
UPDATE: Rapoport reports that the Cowboys have worked out Caleb Hanie, Skelton and Thigpen. Carr is en route to Dallas after his flight was delayed. Dallas has not signed a quarterback yet, per sources informed of the Cowboys' plans.
