Łukasz Brzeski Record: 9-7-1

Earning his shot

Brzeski's Contender Series appearance in September 2021 against Dylan Potter ended in unusual fashion, ruled a no contest after a change of verdict. He was nonetheless signed by the UFC and made his promotional debut in August 2022 against Martin Buday, dropping a competitive split decision. A second straight decision loss followed in March 2023 against Karl Williams, and the rough start continued that August when Waldo Cortes-Acosta stopped him with a first-round left hook.

The signature win and a tough stretch

Brzeski's defining UFC night came in April 2024, when he upset the previously undefeated Valter Walker by unanimous decision, handing the rising Brazilian his first professional loss. The momentum proved hard to sustain in a brutal division. He was stopped by the unbeaten Mick Parkin via first-round TKO at UFC 304 in July 2024, then absorbed another first-round finish from Kennedy Nzechukwu that December. In July 2025, Ryan Spann caught him in a first-round guillotine, leaving Brzeski at 9-7-1 and battling to find his footing among the heavyweight elite.

Fighting style

Brzeski is a finisher by nature, with a 78% career finish rate built on power: five of his nine wins have come by knockout and two by submission. At his best, as in the Walker upset, he uses his size and pressure to break opponents and grind out rounds when the stoppage does not come. The flip side is a vulnerability that has surfaced against the division's hardest hitters and slickest grapplers — four of his losses are by knockout and one by submission, and several have come early. It is the honest profile of a heavy-handed heavyweight who can end any fight but must navigate his own defensive risks against top opposition.
