What physically happened to him? It must be bad, because he can't play. Thus it indicates he needs continued treatment (which he couldn't have if he returned to the game). Do you think the waste started leaking out internally and poisoned him? I've never heard of colon blockage and don't know what causes it or what the result is. But I'm guessing that if he'd gotten treatment right away (instead of trying to be tough), he could've still kept playing and been there today.
