I don't know. I had this injury as high school tight end and had to miss two weeks and wear a brace the rest of the season. I remember I couldn't lift my hand over my head for at least the first week. Long time ago at a low level but it was pretty painful...
Sounds correct. TE has to expose that AC joint again. Seems logical in light of Carr injury. Pain tolerance and risk of reinjury aside it should be quick.
