Gus Chacin had shoulder surgery earlier this week. There apparently was a small rotator cuff tear that was repaired and according to the article Ricciardi said he should be ready for spring training.
Vernon Wells also has a shoulder issue, but not enough of one to stop playing, or even have an MRI on it. But he will have an MRI after the season. This seems a little silly to me, no?
