He literally got cleared by his/their doctor(s) and Jed and other FO guys have said they wouldn't be putting him in a spot to risk another injury/long-term health. Outside of something flukey happening again he shouldn't be any more or less likely to get hurt than anyone else out there now that he got cleared by the doctors and finished his rehabilitation program. In other sports like basketball/football you see re-injury happen or a residual injury happen (i.e. other knee goes out) but those sports have a million times more contact, running/jumping, and switching course of direction quickly over MLB.
