On November 13, 1982, a 21-year-old Mancini met 27-year-old South Korean challenger Duk Koo Kim. Kim had struggled to make the 135lb weight limit, and had to lose several pounds shortly before the fight. It was, according to many observers, a fight filled with action. Mancini finally won by TKO in the 14th round. Moments after the fight ended, Kim collapsed and fell into a coma, having suffered a subdural hematoma on his brain and died four days later.
