BKB 57

BKB 57 brings Britain’s most explosive combat sport series back to indigo at The O2 on 25 July 2026, and it is shaping up to be one of the biggest cards in the promotion’s history. Headlining the night is the return of Mick Terrill, a former Bare Knuckle Boxing Heavyweight World Champion who is one of the sport’s most respected names and a guaranteed crowd-pleaser at The O2. Sharing top billing are Amado and Fernando Vargas Jr., sons of boxing legend Fernando Vargas Sr., making their international and bare knuckle debuts on the night. The Vargas name carries serious weight in the sport and their crossover appeal gives BKB 57 a genuinely mainstream boxing edge. Also confirmed for the card are PFL and Bellator veteran Lee Chadwick, undefeated in bare knuckle competition, Super Welterweight title challenger Martin Reffell, and top-ranked Welterweights Aaron McCallum and Simey Doherty. BKB has been building its London fanbase steadily since its O2 debut, offering something distinctly different from traditional boxing: no gloves, raw technique, and a proximity to the action that gives indigo at The O2 the feel of a classic boxing venue. Doors open at 18:00 with the main event typically getting underway later in the evening. The venue is all-seater with an age restriction of 14+, and under-16s must be accompanied by an adult 18 or over. Tickets are on sale now via AXS, the official ticketing partner of The O2.
