I'd be shocked if he didn't go on the DL. He has a history of shoulder problems, so they will either shut him down for two or three weeks to let the shoulder heal as well as possible and then strengthen it or he will have his surgery now and miss the rest of the season (I certainly don't hope so)
I had that twice, both shoulders. First took me 3 weeks to heal but never fully, and the second on the other shoulder took several month to heal!
Lets just hope he'll lose only a month.
is it his throwing shoulder?
I saw it.
Its his left shoulder.
But he wont be able to swing with that, so doesnt matter.
