Cezary Oleksiejczuk bio
Personal background
Cezary Oleksiejczuk is a Polish middleweight competing in the UFC with a professional record of 17-3. Born on January 6, 2000, he came up through the Polish combat-sports system and began training mixed martial arts at 14 after being encouraged by his older brother, Michał Oleksiejczuk – himself a longtime UFC fighter. Just two weeks into training, Cezary entered an amateur tournament and fought three times in a single day, an early sign of the fearlessness that would define his career. As an amateur he claimed Polish junior titles across three weight divisions. Standing a rangy 6'3" with a 75-inch reach and fighting out of Akademia Sportów Walki Wilanów, he is one of the most physically imposing and finish-oriented prospects to come out of the deep Polish middleweight scene.
Path to the UFC
Oleksiejczuk turned professional in 2018 and built his reputation primarily in Poland's FEN promotion, where he became a champion and racked up wins over experienced regional veterans. He weathered early adversity – two losses in his first eight fights – before settling into a long winning run that established him as one of the best fighters outside the UFC. A breakout moment came in October 2023, when he stopped former Bellator and Cage Warriors standout Chris Fishgold by first-round TKO at FEN 51, a result that put him firmly on the international radar.
Rise to the UFC
Oleksiejczuk kept building momentum on the European scene, and in February 2025 he delivered another statement, blasting out former UFC contender Tom Breese with a first-round TKO at FNC 21. That win, paired with his unbeaten stretch, earned him a spot on Dana White's Contender Series in 2025, where a first-round stoppage of Theo Haig convinced UFC matchmakers to sign him. He made his promotional debut in December 2025 and announced himself in dominant fashion, outpointing César Almeida over three rounds by unanimous decision to push his record to 17-3.
Fighting style
Oleksiejczuk is a finisher with a well-rounded skill set, owning a 65% finish rate built on nine knockouts and two submissions among his 17 wins. His length and power make him a problem on the feet, where the bulk of his stoppages have come by punches, but he is no one-dimensional striker – his early-career submission wins by armbar and choke show a real grappling threat, and his UFC debut demonstrated he can also control and outgrapple opponents to a clear decision. The handful of losses on his record all came in the early-to-middle stages of his career, and his recent form suggests a fighter who has rounded out his game while retaining the punching power that makes him dangerous in any exchange.
Career highlights
- FEN champion and prospect — built a long winning run in Poland's FEN promotion, headlined by a first-round TKO of veteran Chris Fishgold in 2023.
