Kamu Kirk UFC interest has surged again in 2026 after the former professional fighter appeared as a houseguest on Big Brother 28. Known in mixed martial arts as Kamuela “The Jawaiian” Kirk, the Phoenix-based fighter competed in the UFC lightweight division and finished his Octagon career with one victory and two defeats. His combat-sports background, Brazilian jiu-jitsu credentials and outspoken personality have now introduced him to a much broader television audience.
Who Is Kamuela “Kamu” Kirk?
Kamuela Kirk is a professional mixed martial artist from Phoenix, Arizona, who has spent much of his life involved in combat sports. Born April 13, 1994, Kirk entered MMA after developing a strong foundation in Brazilian jiu-jitsu.
His nickname, “The Jawaiian,” reflects his family heritage, with the name combining his Jamaican and Hawaiian roots. That identity has remained closely associated with his public profile throughout his fighting career.
Kirk began training in Brazilian jiu-jitsu as a child and eventually developed into a professional MMA competitor. His grappling background became one of the defining characteristics of his fighting style, but he also developed effective striking and wrestling skills.
His professional career included appearances for Legacy Fighting Alliance, Dana White’s Contender Series and the UFC. He eventually earned his place on the UFC roster and competed three times inside the Octagon.
Kamu Kirk’s Professional MMA Record
Current MMA databases list Kirk’s professional record at 12 wins and seven losses, although some platforms display different totals because of variations in how records are updated.
His victories have come primarily through finishes. Kirk has recorded five wins by knockout or technical knockout and six by submission, with only one victory coming by decision.
That finishing ability is a major part of his reputation. He has secured submissions using techniques including triangles, rear-naked chokes and a guillotine, while his striking has also produced stoppage victories.
Kirk’s record reflects a fighter who has generally preferred to create opportunities to finish rather than rely solely on judges.
His professional career began in 2014, and he spent years building experience before reaching the UFC level. During that period, he also scored notable regional victories, including a first-round submission against UFC veteran Kevin Croom.
How Did Kamu Kirk Reach the UFC?
Kirk’s route to the UFC was not immediate. Like many fighters outside the major promotion, he spent years developing his record on the regional MMA circuit.
His background in Brazilian jiu-jitsu gave him an early advantage on the ground, but progressing toward the UFC required him to become a more complete mixed martial artist.
One of the important steps in his career was his appearance on Dana White’s Contender Series in 2019. Kirk faced Billy Quarantillo during the program, but the fight ended in a defeat for Kirk.
Although the result did not immediately earn him a UFC contract, the experience placed him in front of the UFC’s talent evaluation system.
Kirk continued competing and winning outside the organization before eventually receiving another opportunity to enter the UFC.
That persistence ultimately led to his Octagon debut in 2021.
Kamu Kirk’s UFC Debut Against Makwan Amirkhani
Kirk made his UFC debut on June 5, 2021, against experienced Finnish fighter Makwan Amirkhani.
The matchup represented a significant step in Kirk’s career because Amirkhani already had substantial UFC experience and was recognized for his grappling ability.
Kirk handled the occasion successfully. He fought through three rounds and earned a unanimous-decision victory.
The win gave Kirk a successful introduction to the UFC and moved his promotional record to 1-0.
It was also a particularly meaningful result because Kirk was able to defeat an opponent with a strong grappling reputation. Rather than simply relying on his Brazilian jiu-jitsu background, Kirk showed that he could manage the pace and technical demands of a UFC fight over 15 minutes.
His debut victory established him as a legitimate UFC lightweight and earned him another opportunity against an experienced opponent.
Loss to Damon Jackson
Kirk’s second UFC appearance came against Damon Jackson on March 12, 2022.
Jackson entered the contest with considerable professional experience and presented a difficult matchup for Kirk. The fight ultimately ended in the second round.
Jackson submitted Kirk with an arm-triangle choke at 4:42 of Round 2.
For Kirk, the defeat was his first inside the UFC. It also demonstrated the level of competition he was facing in the promotion, where even experienced grapplers could be punished for small positional mistakes.
Despite the setback, Kirk remained in contention for another UFC opportunity.
His promotional record stood at 1-1, leaving him with an opportunity to rebound in his next appearance.
UFC 290: Kirk Faces Esteban Ribovics
Kirk’s third and final UFC fight to date came at UFC 290 on July 8, 2023.
His opponent was Argentina’s Esteban Ribovics, a dangerous lightweight with strong finishing ability.
The fight lasted all three rounds, but Ribovics earned the unanimous decision. The result left Kirk with a 1-2 UFC record.
Although Kirk did not get the victory, the fight gave him another full-length UFC contest and added to his experience against high-level lightweight competition.
The defeat also marked the end of his UFC run.
There has been no confirmed UFC return for Kirk since that bout.
What Was Kirk’s UFC Style?
Kirk’s style has always been heavily influenced by Brazilian jiu-jitsu.
His submission record demonstrates how important ground fighting has been throughout his career. Six professional victories have come by submission, including multiple triangle and rear-naked-choke finishes.
However, describing Kirk only as a grappler would overlook his striking development.
He has five professional wins by knockout or technical knockout, showing that he can also create finishing opportunities on the feet.
Kirk is listed as a switch fighter, meaning he can operate from both orthodox and southpaw positions. His recorded reach is approximately 75 inches, which provides him with useful physical dimensions for the lightweight division.
The combination of striking, wrestling and submission grappling made him a well-rounded opponent during his professional career.
What Happened to Kamu Kirk After the UFC?
Kirk continued fighting after his UFC career ended.
His next major appearance came outside the UFC, and he returned to the Legacy Fighting Alliance for LFA 196 on November 8, 2024.
Kirk faced Ednilson Santos in the co-main event. The contest went the full three rounds, with Santos earning a unanimous decision.
That fight remains Kirk’s most recent completed professional MMA bout.
Kirk was later scheduled to compete against Jacob Rosales at United Fight League 6 in May 2025. However, Kirk withdrew from the matchup, and the fight was canceled.
No subsequent completed professional MMA fight has been recorded through the latest available information in August 2026.
That means Kirk has been away from active competition for a considerable period.
Is Kamu Kirk Still a UFC Fighter?
Kirk is best described today as a former UFC fighter.
His UFC career consisted of three official fights, with one win and two losses. His last UFC appearance occurred in July 2023.
Being a former UFC fighter does not necessarily mean his MMA career is permanently finished. Professional fighters sometimes return after extended periods away from competition, particularly if they remain active in training.
However, there is currently no confirmed UFC bout announced for Kirk.
Therefore, fans should be cautious about social-media speculation suggesting that he has already secured a UFC comeback.
Why Is Kamu Kirk Back in the Spotlight in 2026?
The biggest reason for Kirk’s renewed visibility is not MMA.
It is Big Brother 28.
CBS selected Kirk as one of the houseguests for the 28th season of the long-running reality competition. His casting immediately stood out because professional MMA fighters are relatively unusual additions to the Big Brother cast.
The show premiered in July 2026, giving viewers an opportunity to see a different side of the former UFC competitor.
Inside the house, Kirk’s physical background made him an obvious potential threat in athletic competitions. He also demonstrated that he understood the strategic side of the game and became involved with multiple alliances.
He won a Head of Household competition and also captured a Power of Veto during his time in the house.
Those victories reinforced the idea that his athletic background could be an advantage in the competition.
Kirk’s Strategy on Big Brother 28
Kirk did not simply rely on his physical ability.
He attempted to build relationships and move between different groups in the house. At various points, his strategic decisions involved shifting loyalties and targeting players he considered dangerous to his game.
That approach eventually created tension.
One of the most significant moments came during his Head of Household reign, when he targeted other competitors and became involved in a confrontation with Jason De Puy.
Kirk’s MMA background also influenced how other houseguests perceived him. Being a professional fighter can create an intimidating image, but it can also make a contestant appear too dangerous to keep around.
That became an important factor as the game progressed.
Kamu Kirk’s Big Brother 28 Eviction
Kirk’s Big Brother game eventually ended after a major strategic reversal.
Rick Devens used a Diamond Power of Veto that allowed him to remove Dee Valladares from the block and place Kirk in her position.
The move dramatically changed Kirk’s situation.
Instead of expecting to remain safe, Kirk suddenly became the replacement nominee. He believed he had enough support to survive, but the situation ultimately went against him.
After losing the Block Buster competition, Kirk was voted out by an 8-1 vote.
His eviction ended his run on the show but immediately generated additional discussion about his strategy, relationships and controversial moments.
Controversy Surrounding Kirk
Kirk’s time on Big Brother 28 also attracted criticism beyond gameplay.
Comments he made concerning drag became a significant subject of discussion, particularly because fellow houseguest Jason De Puy is known for his drag persona, Salina EsTitties.
Following his eviction, Kirk addressed the issue publicly and said he respected personal expression while also emphasizing his own image as an MMA fighter.
The controversy became part of the broader conversation surrounding his Big Brother appearance.
Another controversy emerged in July 2026 after an older video involving Kirk resurfaced online. The clip showed him joking while someone outside his residence was being arrested, including a reference to George Floyd. The resurfaced video prompted criticism across social media.
These incidents have made Kirk’s post-UFC public profile substantially more complicated than his fighting record alone.
What Is Next for Kamu Kirk?
Kirk’s future in MMA remains uncertain.
His last completed fight was in November 2024, and his scheduled 2025 UFL appearance did not take place. There is no verified announcement of another professional fight or UFC return as of August 2026.
At the same time, his Big Brother 28 appearance has created a new avenue for his career.
Reality television can provide former athletes with opportunities in entertainment, media and other public-facing projects. Kirk’s combination of professional fighting experience and reality-TV exposure gives him a profile that is different from what he had before entering the Big Brother house.
Whether he eventually returns to MMA or concentrates on entertainment will depend on his future plans.
For fans searching for Kamu Kirk UFC updates, the most important distinction is between his established UFC history and any future fight speculation. His Octagon record remains 1-2, while his broader professional record is listed by current MMA databases as 12-7.
Kamu Kirk’s Career Legacy
Kirk’s UFC career may have been relatively short, but reaching the promotion represented a major accomplishment after years of training and regional competition.
He entered the UFC with extensive Brazilian jiu-jitsu credentials and demonstrated his ability to compete against established opponents.
His victory over Amirkhani remains the defining win of his UFC career, while his fights with Jackson and Ribovics provided valuable experience against high-level opposition.
His later MMA career continued outside the UFC, and his final recorded fight came against Santos in 2024.
Now, his name is recognized by an audience far beyond MMA.
Big Brother 28 introduced Kirk to reality-TV viewers who may never have watched one of his UFC fights. That transition has made his combat-sports history an important part of understanding who he is, even as his television career becomes a larger part of his public identity.
For now, Kirk remains a former UFC competitor with an accomplished grappling background, a 1-2 Octagon record and an uncertain future inside the cage. His 2026 television appearance has ensured that interest in his career remains high, and any confirmed announcement about a return to professional MMA would likely attract significant attention.
