Cassius Clay retained his WBC, NYSAC, and The Ring heavyweight titles with a third-round knockout of British challenger Brian London at Earls Court Arena. Clay dominated the contest before stopping London at 1:40 of the third round.
Approximately 13,000 fans attended the arena in London to watch Clay’s fifth defense of the heavyweight crown he won from Sonny Liston in February 1964. Although the champion had adopted the name Muhammad Ali two years earlier after converting to Islam, he was still billed and identified as Cassius Clay for the event. Entering the ring with a 24-0 record, Clay was installed as a 15-1 favorite against London, the former British and Commonwealth champion known as “The Blackpool Rock.”
London faced immediate disadvantages in height, reach, and speed. Clay took total control behind a sharp jab, rapid footwork, and fast punch combinations. London struggled to generate any offense, with observers crediting him with only a single solid left jab that caught the champion’s attention in the opening round.
The end came decisively in the third round. Clay trapped London in a neutral corner and delivered a blistering combination of roughly a dozen punches within a few seconds. A left-right combination knocked London to the canvas, where referee Harry Gibbs completed the count.
Clay weighed 209½ pounds for the bout, while London weighed 201½ pounds. The champion secured a guaranteed purse of roughly $252,000 plus a share of television revenue, whereas London earned around $112,000.
London remained remarkably honest about the defeat. He admitted the champion held every advantage, describing himself as “smaller, slower, and lacking the champion’s athleticism.” He frequently joked that he would only accept a rematch if Clay entered the ring “wearing heavy weights around his ankles.” The bout marked the final fight under Clay’s contract with the Louisville Sponsoring Group before Herbert Muhammad took over management duties ahead of his fight against Karl Mildenberger.
