the initial outcome of prior's visit with dr. yocum: posterior shoulder strain -- and not rotator cuff or labrum damage.
the mri has yet to be performed, and that still means 90% of everything. a diagnosis of "strain" is a sort of catchall, as i understand it, of patient pain without an obvious cause that the examining doctor can isolate.
but one can't help but consider that outlook to be good news for the cubs. it seems not to be an obvious rotator cuff tear.
