Terence Allan “Bud” Crawford is an American former professional boxer from Omaha, Nebraska, widely regarded as one of the best fighters of his generation. He turned professional in March 2008 after a successful amateur career and fought as a southpaw across multiple weight classes during a career that ran through 2025[1][3]. Crawford won world titles at lightweight, light welterweight (junior welterweight), welterweight and later moved up to super middleweight, claiming major belts in five weight divisions over his career[1][3]. He became the undisputed light welterweight champion in 2017, unifying the WBA, WBC, IBF and WBO titles — the first undisputed champion at that weight in the four-belt era — and later achieved undisputed status again at higher weights, marking him as the first male boxer in the four-belt era to be undisputed in more than one division[1][2][3]. Known for exceptional ring IQ, switch-hitting ability and counterpunching, Crawford compiled an undefeated professional record and a high knockout ratio, with career statistics widely reported as 42–0 with 31 KOs at retirement[4][8][9]. His notable victories include wins over Ricky Burns (for his first world title), Julius Indongo (to become undisputed at 140 lb), and high-profile defeats of top welterweights that cemented his pound-for-pound standing[1][3]. Crawford received major boxing honors during his career, including Fighter of the Year recognitions from media outlets and boxing writers, and he has been consistently ranked among the sport’s elite by sanctioning bodies and commentators[5][3]. In December 2025 he announced his retirement from boxing, concluding a decorated, undefeated career and leaving a legacy as one of the sport’s most accomplished multi-division champions[4].
