For now, Romo's rehab will consist of rest and immobility, but Garrett will not rule him out of the Sept. 11 season opener against the New York Giants. A source said Romo will miss 6-10 weeks.
"We've gotten a lot of different timetables for when he can return," Garrett said. "We also know that he's played with a broken bone in his back before, so there's no reason for me to stand up here and put a timetable on this. I think a lot of other people outside of this building have suggested they know what the timetable is. That's not the world we live in. We live in the world day by day, do what you can to get yourself better and we'll update you as we go."
