It's funny because a few weeks back Francesa (the radio guy) had a Dr on that basically said if he's having trouble it's probably the bicep and not the shoulder. Looks like he was correct if this becomes the case.
Apparently this happens someone's in rotator cuff injuries because after the shoulder is corrected the bicep sometimes isn't lined up 100% like it was prior to surgery.
He also said it's not a big deal because of the 2/3 month rehab.
Fingers crossed he doesn't need anything done of course.
