BYB 37: Denver Brawl IV

In a battle of two of BYB's most explosive (and undefeated) fighters, men's Super Lightweight champion Harry "The Hitman" Gigliotti defends his title against Jon "Untameable" Barnard.

After their first matchup ended in no-contest, BYB Women's Featherweight champion Helen Peralta and Lailane Mota meet once again in the Trigon for the vacant BYB Super Featherweight Police Gazette Diamond belt.

Plus, undefeated former BYB Super Middleweight champion Sam "The Caveman" Liera returns to the Trigon looking to pick up where he left off. But in order to do so, he will need to once again get past one of the toughest, meanest fighters in the sport, Ryan Jett, whom he went the distance with in the BYB 9 Fight of the Night.
