The condition, known as an Os Acromiale, didn’t appear to be contributing to his left shoulder inflammation at the time, but after weighing other possibilities, doctors recommended a procedure that included inserting screws to stabilize the extra bone in his shoulder. Dr. David Altchek operated on Travis in New York City on Tuesday.
What I don't get is why wasn't something done about this issue earlier in the season? If Travis had this surgery done in September or October, he gets ample time to rehab and get the full spring training to get his body in game shape. As it is now, he'll probably be out throughout spring training and will probably need at least another month of the regular season just to get acclimated to the game again. Yeah, we have a backup option in Goins, but Travis brings much more to the table.
