Tommy Morrison's diagnosis was correct but he claimed it wasn't. He refused to take treatment for it and then lost something like 50 lbs and started to get really sick. Then he went on meds and started to improve. There was an article in ESPN the mag a few years back. He was trying to get back into boxing but nobody would let him box because of his HIV status.
They should have just showed him this replay and told him boxing doesn't need him.
