Sucks to hear this news, but to be honest I am not surprised.
In the game thread, there were a couple people saying he was barely touched and there shouldn't be any injury. I posted that the impact was a classic case of spinal compression and that it was the kind of hit and awkward motion where you could suffer a compression fracture. Here we are a couple days later....and he has an L1 compression fracture. The good thing about the injury is that when it is healed, there isn't really a long recovery period....you are pretty much able to resume activity.
Basically, I think you pretty much roll with Dak unless the team is tanking without Romo. I hate to see it happen, but nothing is fair...time doesn't wait for anyone. Just like Bledsoe's time came to an end basically in the snap of fingers, Romo might be in the same situation. Time to throw our support to Dak....and to be honest, it's kind of exciting.
