Which fighter defeated Georges St-Pierre at UFC 69?

Matt Serra defeated Georges St-Pierre at UFC 69.

The welterweight title fight took place on April 7, 2007, in Houston, Texas. Serra, a significant underdog, stopped the defending champion by technical knockout in the first round. He dropped St-Pierre with punches and continued attacking until the referee ended the contest.

St-Pierre had won the championship from Matt Hughes at UFC 65 and entered UFC 69 as the clear favorite. Serra had earned his title opportunity by winning The Ultimate Fighter 4, making the upset one of the most memorable results in UFC history.

Serra’s reign was brief. At UFC 83 in Montreal, St-Pierre defeated him by second-round TKO to regain the welterweight championship. The two fights are therefore often discussed together, but UFC 69 was the bout in which Serra captured the title.
