Karl Moore Bio
Karl Moore (born October 24, 1991) is a Northern Irish mixed martial artist who competes in the Light Heavyweight division. Standing 191 cm tall with a 191 cm reach and competing at 93 kg, he has built a reputation as one of Northern Ireland’s most accomplished light heavyweights. Moore is widely known for his time in Cage Warriors, where he held the Light Heavyweight Championship, and for his run as a Light Heavyweight Title contender in Bellator MMA. He has also competed in the Professional Fighters League, representing SBG Ireland throughout his professional career.
Early Life and Background
Karl Moore was born and raised in Belfast, Northern Ireland, and grew up in the Twinbrook area of the city. From a young age, he was drawn to combat sports, partly inspired by the larger-than-life persona of professional wrestler “Stone Cold” Steve Austin and partly by his father’s own background in martial arts. Before committing to a single discipline, Moore explored several combat arts, including Brazilian Jiu-Jitsu, judo, and Thai boxing, before settling on the all-encompassing format of mixed martial arts.
At the age of 16, Moore began formal MMA training at Fight Academy Ireland Gym in Poleglass, where his commitment to the sport began to take shape. The early years were financially difficult, with Moore working multiple jobs, living on a tight budget, and at times sleeping on a gym mattress to stay close to training. During this period, he crossed paths with Gerry Storey, a legendary figure in Belfast’s boxing scene, and under Storey’s guidance he stepped into the boxing ring once, recording a victory in that single bout.
Path to MMA
Moore launched his professional mixed martial arts career in 2011, debuting at Battlezone FC 4. He quickly announced himself on the UK regional scene by capturing the Battlezone FC Light Heavyweight Championship with a first-round triangle choke victory over Rimantas Pukas. He followed that breakthrough with a string of regional wins, most notably a victory over future UFC fighter Cyril Asker, establishing himself as one of the most promising light heavyweights in the British Isles.
His first significant setback came at BAMMA 22 on September 19, 2015, when he was submitted by Paul Craig via guillotine choke in the second round. Undeterred, Moore bounced back with two first-round finishes, which set up a title opportunity at Cage Warriors 81 on March 4, 2017. There, he claimed the vacant Cage Warriors Light Heavyweight Championship with a hard-fought unanimous decision over Josh Clark, marking his arrival on the European stage.
Karl Moore Career
Early Career (2011–2017)
Moore’s early professional years were spent grinding through the UK and Irish regional circuit, where he built a reputation as a fast finisher and a well-rounded fighter. His first-round submission of Rimantas Pukas at Battlezone FC 4 gave him an early title, and subsequent wins over established names, including Cyril Asker, sharpened his résumé. The lone loss to Paul Craig in BAMMA served as a learning experience, and two quick first-round finishes reignited his momentum heading into Cage Warriors.
Capturing the vacant Cage Warriors Light Heavyweight Championship in 2017 was the defining result of this phase. The unanimous decision win over Josh Clark confirmed Moore’s status among Europe’s top light heavyweights and earned him a high-profile opportunity to chase a second Cage Warriors title at heavyweight.
Cage Warriors Heavyweight Challenge (2018)
In March 2018, Moore moved up in weight to challenge Mauro Cerilli for the Cage Warriors Heavyweight Championship at Cage Warriors 92 in London, England. The experiment at heavyweight did not go as planned, as Cerilli landed a devastating knee followed by strikes, ending the bout by first-round knockout. Despite the loss, the appearance demonstrated Moore’s willingness to test himself against the very best across weight classes.
Bellator MMA Era (2019–2024)
Moore signed with Bellator MMA and made his promotional debut on September 27, 2019, at Bellator 227 against Lee Chadwick, winning by split decision. After a period of inactivity, he returned to the Bellator cage on September 23, 2022, at Bellator 285, where he submitted Karl Albrektsson with a second-round face crank. He followed that performance with a unanimous decision win over Maciej Różański at Bellator 291 on February 25, 2023, and another unanimous decision victory over Alex Polizzi at Bellator 297 on June 16, 2023.
Moore’s biggest opportunity in Bellator came on March 22, 2024, at Bellator Champions Series 1, when he faced Corey Anderson for the vacant Bellator Light Heavyweight World Championship following Vadim Nemkov’s vacancy of the title. Although Moore entered the bout as a top contender, he was outworked in the wrestling exchanges and lost by unanimous decision, ending his Bellator title bid.
Professional Fighters League (2025)
On March 4, 2025, the Professional Fighters League officially revealed that Moore would join the 2025 PFL Light Heavyweight Tournament. In the quarterfinal round, he faced Antônio Carlos Júnior on May 1, 2025, at PFL 4, and lost the bout by split decision. On April 30, 2025, it was announced that his opponent had tested positive for recombinant erythropoietin via an out-of-competition sample collected on April 9, 2025, resulting in a one-year USADA suspension beginning on that date. It was also announced that Moore had been released from the PFL roster prior to the suspension being issued.
Notable Events and Milestones
Moore’s career is highlighted by the Cage Warriors Light Heavyweight Championship, the run of four consecutive Bellator victories that pushed him into a world title fight, and the chance to compete in the 2025 PFL Light Heavyweight Tournament. His first-round triangle choke debut win, his unanimous decision capture of the Cage Warriors title, and the face-crank submission of Karl Albrektsson remain the most memorable finishes of his career so far.
Karl Moore Career Wins
Across his professional career from 2011 to 2025, Karl Moore compiled an MMA record of 12 wins and 4 losses in 16 total bouts.

The majority of his finishes came during his UK and Cage Warriors years, while his Bellator run featured three unanimous decisions and a slick second-round face-crank submission.
Cage Warriors Highlights
Moore’s signature Cage Warriors moment arrived at Cage Warriors 81 on March 4, 2017, when he outpointed Josh Clark over the distance to claim the vacant Light Heavyweight Championship. He later attempted to add the Cage Warriors Heavyweight Championship against Mauro Cerilli at Cage Warriors 92, falling short in the first round. Those back-to-back title opportunities cemented his legacy as one of the promotion’s most recognizable light heavyweights.
