Not much else is known at this point, other than that it is being called minor, but Divish is reporting it via Twitter. Anyways, yeah, any thoughts of Erik Bedard returning this season are further nailed.
More, according to Divish:
So, exploratory then. Probably necessitated by Bedard's shoulder not getting any better with rest and rehab. There is little chance that they go in and find anything that is both causing the pain and minor enough to fix and recover from before the season ends. It's not like he has a splinter stuck in there and getting rid of that will make it all go away.
The surgery will inspect labrum to see level of fraying and also inspect bursa complex to see if anything is irritating it.
