Event Information
BKB BARE KNUCKLE BOXING RETURNS TO ITS LONDON HOME, INDIGO AT THE O2 ON SATURDAY, FEBRUARY 21, 2026. BKB 51 will be headlined by “The Emperor of Bare Knuckle” Marko Martinjak defending his BKB Bridgerweight Championship against former BKB Heavyweight Champion “Hurricane” Ike Villanueva. Headlining the card will be the first Bridgerweight title defense of Zagreb, Croatia’s 12-2 Marko Martinjak. This past October in Leeds, UK, the then Cruiserweight Champion Martinjak defeated Dan Podmore to win the Bridgerweight title and become BKB’s second two-division world champion. Shortly thereafter, Martinjak relinquished the Super Cruiserweight belt to concentrate on the Bridgerweight division. His opponent Ike VIllanueva (Houston, Texas, USA) is the 5-2 former BKB Heavyweight Champion. Villanueva, a former UFC veteran, was successful in his initial Bridgerweight matchup this past November against former Martinjak trilogy foe Jarome Hatch.
