Dallas Cowboys owner Jerry Jones, during a weekly radio interview on 105.3 The Fan, says quarterback Tony Romo is out for the season after suffering a hairline fracture to his left clavicle, according to The Dallas Morning News' Jon Machota.
Jones added that a CT scan Friday morning confirmed the finding and that Romo will not need surgery.
Romo went down on the final play in the third quarter of the team's Thanksgiving Day game against the undefeated Carolina Panthers.
Slow to get up, it quickly became obvious that Romo had re-injured his collarbone by the way he pounded the turf in frustration while still on his back.
The latest news from around North Texas.
Romo missed seven games this season after breaking his clavicle during Week 2's game against the Eagles -- a game the Cowboys would go on to win.
The team was quarterbacked first by backup Brandon Weeden (now cut), who went winless in four starts, and then Matt Cassel who went winless in three.
Romo returned in Week 11 to lead the team to victory over the Miami Dolphins. The Cowboys were a surprising favorite to beat the undefeated Panthers, who are now 11-0 on the season. With Thursday's loss the Cowboys are now 3-8 and in possession of the worst record in the NFC.
The fracture is the third for Romo to his non-throwing shoulder in his nine-year career. Romo first suffered the injury in the sixth game of the 2010 season. He never returned, though with the Cowboys at 1-5, there was no point in rushing it at the time.
