My sports med doc friend says that if nothing is broken then he’s lucky, but that an MRI might show a coranoid process (ulna)fracture.
He doesn’t think it’s career threatening because it didn’t look like a complete dislocation. And sometimes these just sublux.
If there was a complete dislocation, you’d likely have seen a fractured radius on the x Ray. But obviously more tests are necessary.
This comes with caveat that this is all off of a twitter video and he’s half asleep because he’s in California and it’s 5 am.
