Muhammad Ali defended the heavyweight championship with a 15th round TKO of "Bayonne Bleeder" Chuck Wepner in Richfield, Ohio in 1975.
Ali, a heavy favorite, kept Wepner on the outside with his jab for much of the fight. Occasionally Wepner managed to get inside and maul, but not consistently. Wepner seemed frustrated that he felt referee Tony Perez wouldn't allow him to do more in the clinch.
In round 9, just after Wepner said something to Perez about letting him work inside, Wepner sent Ali to the canvas by landing a right to the body as he stepped on Ali's foot. Perez called it a knockdown.
"[Perez] is a dirty referee," Ali said, insinuating that Perez favored Wepner in the bout. "He's a dirty dog. He'll never referee another of my fights."
Ali rose and wound up rocking Wepner with right hands a few rounds later, including a right hand that nearly turned Wepner around in round 13. The following round saw Wepner following Ali around, attempting to find something to end the fight in his favor.
Ali's corner implored him to end matters. "Get rid of this bum, champ!" screamed "Bundini" Brown. "Get rid of this bum!"
Wepner wasn't a bum, but that's what Ali did in round 15. With Wepner clearly weakening, Ali dialed up his offense and landed a hard right hand on Wepner as he lurched around the ring, wide open. Wepner sailed to the canvas, and the fight was stopped as he tried to get up.
"Many people thought this fight would be a joke, but you saw yourself a good fight," Ali quipped afterward. He's a good, awkward fighter. Better than you give him credit for."
Wepner, somewhat bitter about the result, said, "I thought I was in this thing all the way to the end. How many guys do you know that went 15 rounds with Muhammad Ali and were still punching at the end?"
Tony Perez never refereed another Muhammad Ali fight.
