An NBC 5 crew covering the team was in the locker room at the time of the incident and said they heard what sounded like someone falling in the shower.
That's when players started calling for trainers and medics.
A stretcher was brought in and players were asked to leave the shower area while members of the media were asked to turn off their cameras.
Romo refused the stretcher and was escorted back to his locker, but left as soon as he realized he was surrounded by members of the press.
Sources tell NBC 5 and ESPN, Romo may have a suffered a rib injury during the game.
Romo did manage to hold his usual post game press conference but seemed winded and a little out of it while speaking with reporters.
