Bare Knuckle Boxing continues its drive toward the top of the bare knuckle food chain. Later this month in Miami, BKB will put on an event at the James L. Knight Center with Roberto Duran Jr. making another appearance in the promotion's Trigon. He'll face Ryan "The Bull From Hull" Spivey.
In addition to Duran, the card will also feature former ranked UFC fighter Aspen Ladd making her promotional debut against Bianca Daimoni. Let's talk bare knuckle.

One detail worth keeping straight: Ryan Spivey is not Austin Spivey. Duran Jr. stopped Austin in April. Ryan arrives from the United Kingdom with his own momentum, and he has said the elder Durán was one of his boxing idols.
CEO David Tetreault said Duran Jr. "carries one of the great names in boxing history" and has proven he can back it up inside the Trigon. Duran Jr., for his part, has framed the fight around separating himself from his father's shadow. "This is about my legacy now," he said.
