Tony Romo re-injured his left shoulder on the last play of the third quarter in Thursday's game versus the Carolina Panthers.
Romo's shoulder took the brunt of the pressure on a Thomas Davis sack. The Dallas Cowboys' quarterback immediately grabbed the shoulder and pounded the turf in frustration. Down for a minute or two, he eventually walked off holding his left arm gingerly against his chest.
Romo immediately departed for the locker room to undergo X-rays.
It's worth nothing that Romo was told by doctors that he was still at risk of re-breaking his collarbone when he returned to face the Miami Dolphins two weeks ago, FOX Sports' Jay Glazer reported.
