Pride officials then signed Mezger to fight Kazushi Sakuraba, who at the time was considered to be one of the best pound for pound fighters in the world. The fight took place at the Pride Grand Prix 2000 Opening Round. Mezger took the fight on two weeks notice and had a broken foot going into the fight. The contract that Mezger signed stipulated that the fight would be one 15-minute round with no overtime, in contrast to the other fights which were to have an extra round in the case of a draw. The fight mostly consisted of Mezger controlling the fight by stopping Sakuraba's takedown attempts while landing strikes from the outside. The round ended and Mezger expected the fight to go to the judges, but Pride officials wanted the fight to go to overtime. This resulted in one of the largest and most publicized controversies in MMA history.
