Do we know for a fact that it's dislocated? Because on Twitter, Patrick said "appeared to dislocated" and in this story it just says "dislocated."
I've dislocated my shoulder three times. Got surgery after the first one. Second dislocation happened three years later after I'd slacked on my therapy exercises and drunkenly fell onto a sidewalk at a weird angle (yeah, I was a dumb frosh).
My ortho was shocked that it'd come out of socket again. That's three years after surgery and with blunt trauma.
I have a tough time believing that Braxton's shoulder came out on its own, without any trauma, only seven months post-op.
I had another injury to my shoulder (which might have been the scar tissue popping off, I never knew for sure) that felt like I'd popped it out, and I was on the ground in pain for a few minutes. Turns out there wasn't any structural damage. This happened throwing a baseball seven months after my surgery.
