The key moment in the fight came with ten seconds to go in the last round, when Chacon struck suddenly, connecting with a right to Limón's chin and sending Limón to the floor. While Limón got up, a mandatory standing count was carried by the referee, and by the time the fight was allowed to go on, there was only two seconds left in the bout. As it turns out, the knockdown made Chacon a world champion for the second time, just as he had promised his wife and family he would be, when judges Angel L. Guzman and Tamotsu Tomihara gave him the fight by a single point, 142-141 and 141-140 respectively (in boxing, a knockdown usually gives a fighter both the round and an extra point in a judge's scorecard, without the knockdown, Chacon would not have won). The third judge, Carlos Padilla, scored the bout 143–141, also for Chacon.
