So... I had put a post in here the other day after MTCasey, but I deleted it because I didn't have a second source like I wanted, and didn't feel comfortable putting it out there.
But now that the university has put this out there (convenient they didn't respond to my request about the matter, but that's another story...), I'll share the rest of what I was told.
The way it was broken down to me, Brent was injured during the bowl game, but played through it. He has a torn labrum, according to my source, that was further aggravated through weight lifting.
He tried to throw for the first time a couple of weeks ago, and was in severe pain. He went to see Dr Andrews, who put him on a two-week therapy cycle that ultimately did not work, hence the decision for surgery.
While big Stock says they're just going in to "clean things up", surgery to repair a torn labrum is anything but that.
I was told the recovery time Brent was given was six months, which would put him on target to return at the end of August/first of September. I'm sure he'll start right away, but he will not go through spring or fall camp according to my source.
