Robert Duran Jr. Earns First-Round TKO Over Ryan Spivey at BKB 58
The super welterweight fight ended at 1:49 of Round 1 after Spivey appeared to injure his knee. Duran Jr. had already put Spivey down during the brief exchange, and the British fighter tried to continue despite clear trouble with his leg. He was dropped again and could not rise to resume, prompting the stoppage inside the BKB Trigon.
It was a short finish, and one that needs the context: Duran Jr. was officially credited with a TKO win, not a standard knockout. The stoppage came after Spivey’s injury limited his ability to move and defend himself, though Duran Jr. had started quickly and was landing effectively before the fight was waved off.
The result moved Duran Jr. to 4-2 in BKB competition, with four stoppage wins. His opponent, Spivey, left Miami with a 4-3 bare-knuckle record.
Duran Jr., 37, fought on the August 29 card at the James L. Knight Center, where he had the advantage of competing in his hometown. He is the son of Roberto Duran, the Panama-born boxing icon and former four-division world champion, but the younger Duran has continued to build his own record across professional boxing and bare-knuckle competition. Before BKB 58, he entered with a 12-4 pro boxing record and a 3-2 mark under the BKB banner.
