The Cowboys project a six- to eight-week recovery for Romo following his surgery.
Romo will have a CT scan on his collarbone in the next week. That scan is to determine whether sufficient healing has taken place to support the hardware that surgeons will attach to strengthen the left clavicle.
Since 2010, Romo has broken the collarbone three times, including twice last season. The initial break came Sept. 20 against the Philadelphia Eagles, and then after missing seven games, he suffered a hairline fracture after a hit in the Cowboys' Thanksgiving Day loss to the Carolina Panthers.
"I think we know which way we're siding and we've had exhaustive discussions about it," Romo said Saturday of the possibility of surgery. "Really it's just about being there for your teammates. If I play, I know what I mean to our team. I just need to do everything in my power to make sure I'm on the football field."
The day after the 2015 season ended, Romo said he was looking at different options that could help him avoid future collarbone injuries. The Cowboys were 1-11 without Romo and want to do whatever is possible to ensure his damaged shoulder can withstand contact in the future.
