Analysis
Mateusz Legierski is a Polish mixed martial arts fighter, OKTAGON lightweight champion since November 2025. The first holder of the belt in 2020, he reclaimed it five years later after a stint with KSW.
Career
Mateusz Legierski was born on July 23, 1996, in Koniaków, Poland, and trains at Octagon Team Cieszyn. He turned professional in MMA in September 2018 with a TKO by punches over Kamil Czyżewski at PLMMA 76 in Białystok, then submitted Konrad Furmanek the following month by triangle choke at Gala Sportów Walki 9 in Międzychód. In 2019, he strung together three TKO wins on the fledgling OKTAGON circuit, over Michal Konrád in Ostrava, Ronald Paradeiser in Bratislava, then Jakub Bahník by a one-punch knockout in Prague. He also competed in kickboxing, where he won his only recorded fight by flying knee knockout, in June 2018 at Silesian MMA 1.
OKTAGON Career, First Reign
On February 15, 2020, at Oktagon Prime 3, Legierski beat Miroslav Štrbák by split decision to win the organization’s first-ever lightweight belt. He vacated it in May 2020 to join KSW, where he beat Francisco Barrio by majority decision in November 2020, before losing by TKO due to punches to Roman Szymański in the second round of KSW 65 in December 2021, his first professional loss after seven straight wins.
Return to OKTAGON and Second Reign
Legierski returned to OKTAGON in 2022. He submitted Matouš Kohout twice by rear-naked choke, at OKTAGON 34 in July 2022 and again at OKTAGON 54 in March 2024, sandwiched between decision wins over Matěj Kuzník at OKTAGON 43 in May 2023 and Karol Ryšavý at OKTAGON 47 in October 2023. After a win over Akonne Wanliss at OKTAGON 58 in June 2024, he suffered his second professional loss, on points to Losene Keita, at OKTAGON 61 in September 2024. On November 22, 2025, at OKTAGON 80 in Munich, he beat Attila Korkmaz by unanimous decision over five rounds to reclaim the lightweight belt, vacant since his 2020 departure. He made his first defense on June 20, 2026, at OKTAGON 90 in Berlin, by TKO due to punches over Gökhan Aksu, stopped in the first round after three minutes and twenty-three seconds.
Fighting Style
Legierski combines a submission base, with three wins by rear-naked choke or triangle, with a boxing game that has brought him five finishes by KO or TKO, including the one that let him defend his belt against Gökhan Aksu. Six of his wins have gone to decision, some over five full rounds, a sign of a style that holds its own over distance as much as it seeks the finish. His only loss before the final bell, against Roman Szymański, remains the one blemish on a record otherwise built on consistency at Octagon Team Cieszyn.
