BYB returns to Denver, Colorado, USA for a night of hard-hitting action February 22 at the Stockyards Event Center for BYB 37 Denver Brawl IV. The main event will feature two of BYB’s most explosive fighters when champion Harry “The Hitman” Gigliotti defends his BYB Men’s Super Lightweight title against undefeated Jon Barnard. In the co-main event, BYB Featherweight champion Helen Peralta will look to become BYB’s first 2-division women’s champion when she faces Brazil’s Lailane Mota for the vacant BYB Super Featherweight championship. Plus, undefeated former BYB Super Middleweight champion Sam “The Caveman” Liera returns to the Trigon in a rematch with one of the toughest, meanest fighters in the sport, Ryan Jett.
