This post cannot be stressed enough. We have had conflicting reports on what exactly the injury was.
UConn Report, Oz from TOS, and Borges in his NH register article are all saying shoulder separation (though Borges in his tweet contradicts his article by calling it a dislocated shoulder). That is a AC joint injury, not a true shoulder dislocation.
Amore is saying shoulder dislocation and in his article actually describes a true dislocation and spontaneous relocation of his shoulder joint.

It would be nice to have definitive confirmation on what the injury was because it drastically changes the treatment options.
My pure speculation is that it was a true shoulder dislocation and, if this is his 2nd, needs a MRI to evaluate his labrum. I'm sure the team docs have one pending.
Doc hoops, where are you practicing?
