MIAMI, FLORIDA (August 5, 2026) – BKB Bare Knuckle Boxing, the world’s largest professional bare knuckle boxing organization, today confirmed that Robert Duran Jr., son of four-division world champion Roberto Duran, will return to the Trigon in his hometown against Ryan “The Bull From Hull” Spivey at BKB 58 on Saturday, August 29, 2026, at the James L. Knight Center in Miami.
The son of Roberto Duran, widely considered one of the greatest fighters of all time, Duran Jr. has carved out his own path in the sport, turning pro at 29 after only a handful of years training seriously. Fighting out of Miami, the 37-year-old enters the bout with a 3-2 BKB record and a 12-4 professional boxing ledger, and he arrives on a high note, having stopped Austin Spivey by TKO at BKB 53: The Harder They Fall in April.
Ryan Spivey, a five-fight veteran of Bad to the Bone and the promotion’s former English Champion, brings a 4-2 bare knuckle record and an unbeaten 1-0 mark since joining BKB, most recently stopping Sam Clarke at BKB 54: Mayhem In Manchester in May. The Hull native has cited Roberto Duran among his own boxing idols growing up, adding another layer of intrigue to about that will see him share the Trigon with the legend’s son.
Robert Duran Jr. said: “This is my city, my home, and I’m bringing that energy into the Trigon. My father sealed his envelope a long time ago, this is about my own legacy now. Spivey’s tough, but I’ve got business to finish and I’m going to finish it in front of my people in Miami.”
David Tetreault, CEO of BKB Bare Knuckle, said: “Robert Duran Jr. carries one of the great names in boxing history and he’s proven time and again that he can back it up inside the Trigon. Putting him in Miami against a fighter like Ryan Spivey, who’s earned every bit of his growing reputation, is exactly the kind of matchup our fans expect from BKB. This is must-see action.”
The Duran Jr.-Spivey clash joins a stacked BKB 58 card that already features undefeated BKB Heavyweight World Champion Gustavo “The Cuban Assassin” Trujillo defending his title against Mark O’Neil, Olympic gold medalist Yuriorkis Gamboa making his BKB debut against Yesner “Cuajadita” Talavera, and former UFC title contender Aspen Ladd making her BKB debut against Bianca Daimoni.
