Joe Frazier vs. Oscar Bonavena II

Undefeated knockout artist Joe Frazier is knocked down and forced to go the distance for the first time in his professional career when he takes on the tough Oscar Bonavena. Despite being staggered by a left hook at the end of the first round, Bonavena comes back to floor Frazier with a huge right hand in the second. Frazier gets up on unsteady legs and is sent stumbling onto his rear by a left hook from Bonavena. Somehow, Frazier recovers and proceeds to tear into Bonavena with heavy thunder for the rest of the bout, rocking him with a left hook and right hand in the fifth. Bonavena manages to light Frazier up once more in the tenth and final round, but Frazier has enough rounds in the bag to get the split decision victory.

In his second fight since returning from a three-and-a-half year layoff, Muhammad Ali takes on the rugged Oscar Bonavena for a shot at the Heavyweight Championship held by Joe Frazier. Ali taunts Bonavena during the early rounds and opens a cut under Oscar's left eye while trying to realize a ninth-round knockout prediction. As the fight appears headed the distance, Ali finally floors Bonavena with a huge left hook in the fifteenth round. Bonavena struggles to his feet but goes down twice more on left hooks, forcing Referee Mark Conn to stop the bout on the three-knockdown rule. Having become the only man to stop Bonavena, Ali looks toward a super fight with Frazier.
