Yeah, it depends on how many dislocations the shoulder has had. Kennelly's shoulder has probably been dislocating many times, and so his ligaments are loose and not to much more damage occurs. (However every dislocation causes some damage).
It looked like it was a new injury to Sinclair with the obvious discomfort he was in.
Whatever the case, it was a mistake to put Sinclair back on after a dislocation, which is proven because they didnt send him back out after the 2nd.
