Fight: Duk Koo Kim vs. Ray Mancini
This is the fight that changed boxing forever. Korean contender Duk Koo Kim took a vicious beating at the hands of Ray Mancini. At one point he was hit 39 times in a row. The ref let the fight go on and after getting knocked out in the 14th round, Kim collapsed and fell into a coma. He died four days later. Referee Richard Green and Kim's mother both committed suicide in the following months. The aftermath of Kim vs. Mancini led to 12-round bouts being the maximum length for prize fights. #shitisreal
