Most great mixed martial artists carry at least one defeat they never had the chance to answer. Georges St-Pierre finished with a rare kind of symmetry: a 26-2 professional record, with later victories over both men responsible for those two losses. He did not erase the defeats, but he closed every competitive loop they created.
Matt Hughes exposed the first gap
St-Pierre’s first loss came against welterweight champion Matt Hughes at UFC 50 in October 2004. Still early in his UFC career, the Canadian challenged one of the division’s defining champions and was submitted by an armbar near the end of the opening round.
The setback did not last on the record without an answer. After five straight victories, St-Pierre met Hughes again at UFC 65 in November 2006. This time he stopped Hughes with strikes in the second round and won the welterweight title. The UFC’s history of landmark welterweight title fights describes the rematch as a changing of the guard.
They fought once more at UFC 79. St-Pierre won the rubber match by armbar—the same broad submission family that had ended their first encounter—and captured the interim title.

From a historic upset to redemption
St-Pierre’s second defeat was even more shocking. In his first defense after beating Hughes, he faced Matt Serra at UFC 69 in April 2007. Serra hurt him with punches and earned a first-round stoppage, taking the championship in one of the UFC’s most famous upsets.
St-Pierre rebuilt again. He defeated Josh Koscheck, beat Hughes for a second time, then faced Serra in a title-unification rematch at UFC 83 in Montreal in April 2008. St-Pierre controlled the fight and won by second-round stoppage after knees to the body. The result restored the undisputed welterweight title and avenged his final career loss.
The complete sequence can be checked in the official UFCStats fight history, which lists the losses to Hughes and Serra alongside the later wins over both.

Thirteen wins after the last defeat
St-Pierre never lost again. Beginning with the Koscheck victory after UFC 69, he won his final 13 fights. That run included nine successful welterweight title defenses, according to the UFC’s official retirement announcement.
After stepping away in 2013, St-Pierre returned almost four years later at UFC 217. He moved up to middleweight, submitted champion Michael Bisping in the third round and became a champion in a second weight class. ESPN’s retirement report confirms the final 26-2 record and the route from his first title win over Hughes to the comeback against Bisping.
The remarkable part is not that St-Pierre was unbeaten—he was not. It is that each defeat became evidence of adaptation. One loss came by submission, the other by strikes; he returned with answers for both opponents, reclaimed his championship and finished his career on top.
