Terence Crawford, 38, retired undefeated after winning the unified super middleweight title in September 2025.

Undefeated boxing champion Terence Crawford, 38, has announced his retirement from professional boxing, ending a 17-year career with a perfect 42-0 record and 31 knockouts. The Omaha native, who became the first male boxer in the four-belt era to hold undisputed titles in three weight classes, retired after defeating Saul "Canelo" Alvarez in September 2025 to claim the unified super middleweight crown. Crawford, who held world titles in five divisions, cited personal fulfillment and a desire to leave on his own terms, emphasizing his journey from humble beginnings. Though stripped of the WBC title over unpaid sanctioning fees, he remains the reigning WBA, IBF, and WBO champion. His career, marked by dominance, precision, and no losses, concludes as one of the most accomplished in modern boxing history.
