BYB Extreme Fighting Series

BYB Extreme Fighting Series (BYB) is a bare knuckle fighting organization founded in 2015 by former MMA fighter Dhafir ("Dada 5000") Harris and former NASCAR team owner Mike Vazquez whose HRT Motorsports was NASCAR's first Hispanic team. Harris rose to fame from his staging of backyard bare knuckle fights which went viral online and subsequently became the subject of the Billy Corben documentary, Dawg Fight. BYB is an abbreviation of "Back Yard Brawl," a nod to the company's origins. BYB's fights are held in it patented "Trigon" ring or cage, which it touts as the smallest fighting surface in combat sports.

In June 2023, beIN SPORTS announced it secured an exclusive media rights deal with BYB in North America to broadcast "Best of BYB" archive shows as well as five live events, making it the first bare knuckle fighting to air live on linear television. In 2024, BYB announced expanded coverage to Fight Network and Fuse.

History
BYB announced that its premiere event, Battleship I – originally scheduled to take place aboard the deck of the Resorts World Bimini Superfast – would air on June 5, 2015, shortly after Dawg Fight premiered on Netflix. The event was scrapped from the cruise ship with the organization citing inclement weather, and subsequently held indoors at an undisclosed location in Miami.

BYB went on hiatus following Dada 5000's return to the ring at Bellator 149. The promotion would host BYB 2: Brawl for it All in Cheyenne, Wyoming on April 5, 2019, at Cheyenne Ice & Event Center. That event started the current run of numbered BYB events in states including Florida and Mississippi, as well as internationally in London.

Partnership with BKB
In November 2021, BYB announced a talent exchange partnership with UK-based BKB in which each promotion sends fighters overseas to be featured on the other's cards. The series kicked off at BYB 8 with BKB's Barrie Jones knocking out BYB's Luis Melo in the first round. Through 2022, the companies have hosted 15 trans-continental bare knuckle matchups.

On October 16, 2022, the event featured a mix of BYB vs. BYB, BKB vs. BKB, and BYB vs. BKB fights. The show featured a number of firsts including the first sanctioned professional female bare knuckle fight in UK history (Jamie Driver def. Sonya Dreiling), the first female title match in UK history (Jozette Cotton def. Miranda Barber for the BYB Super Welterweight and Police Gazette Diamond Belt), and Seth Shaffer defeated Carlos Guerra to win the inaugural BYB Welterweight title as well as the Police Gazette Diamond Belt. The event was broadcast live on Stadium.

Acquisition of BKB
On May 8, 2024, it was announced that BYB Extreme had acquired BKB. Founded in 2015 by Jim Freeman and Joe Smith-Brown, BKB had hosted 40 events prior to the acquisition, some which featured fighters from BYB Extreme. Despite BYB acquiring BKB, both Freeman and Smith-Brown will stay with BYB Extreme in an executive capacity and will oversee the continued expansion of BYB Extreme into Europe.

Trigon
In 2015, BYB and its parent company Lights Out Productions filed for a patent on its triangular shaped ring and cage, which they note is the smallest in combat sports. The patent was granted on December 19, 2017.

In 2021, Triller announced that it would host Triad Combat in a triangular ring. BYB in turn filed a lawsuit against alleging copyright infringement.
