I've been trying to do a little research on it... From my limited knowledge, it looks like one of those things that has a pretty wide range of recovery times. Some people can bounce back from it quick, while others take longer. With it being Collins's receiving hand, I'd be really surprised to see him behind the plate until the start of SEC play at the absolute earliest- and even then, that would be pretty damn gritty. Maybe he could DH a little before then, who knows.

All you can really do is make him drink a bunch of milk and hope for the best at this point.
