Staff infections are very painful and hard as hell to heal,you guys joke like it is nothing and he should just fight though it but that's not possible. I just seen a special not long ago about football players getting it and they said they thought it was nothing at first and they would just play through it but it became more painfull and crippling then any hit they ever took on a football field, it ends careers and is so common in locker rooms the NFL put a full out assault against it trying to sanitize everything which is a full time battle.

On another note about fighting with one hand, there was at least one pro fighter with only one hand, I think it was his right that was gone just above the elbow?, they put a glove on it and allowed him to fight and he did ok considering his right was a stub. I don't know his name and just searched for him with no luck but I remember watching him a couple times years ago maybe on espn??
