Mateusz Legierski's record and the OKTAGON lightweight title fight with Ivan Buchinger

Mateusz Legierski's last two fights were both for the OKTAGON lightweight title, and they could hardly have gone differently: five full rounds against Attila Korkmaz, then 3:23 of round one against Gökhan Aksu. On 21 November he meets Ivan Buchinger, 46-10-0, in the main event of Oktagon 98 in Třinec.

Mateusz Legierski record: 14-2 and the lightweight belt

Legierski is 30, born on 23 July 1996 in Poland, and fights under the nickname "Dynamite". He stands 178 cm tall, made his professional debut on 22 Sep 2018 and today carries a 14-2-0 record as OKTAGON lightweight champion. He is on a two-fight win streak and is 4-1 in his last five.

His two losses came by one KO/TKO and one decision. The decision loss is the one that still shows in his recent form: Losene Keita beat him over three rounds at OKTAGON 61 on 21 Sep 2024. Both fights since then were title fights, and he won both.

How the wins came

Legierski's 14 wins split cleanly: seven by decision, four by KO or TKO and three by submission. That puts his finish rate at 50%, counted as the share of wins that ended by KO, TKO or submission.

The split says something about how he developed. In 2022 and 2023 he took three straight decisions, over Matouš Kohout, Matěj Kuzník and Karol Ryšavý. Then he met Kohout again at Oktagon 54 on 2 Mar 2024 and needed only 4:38 of round one to submit him. It is the clearest before-and-after in his record: same opponent, a very different result.

His decision win over Akonne Wanliss at OKTAGON 58 followed three months later, so the late-career picture is not simply a fighter who stopped going to the scorecards. He still wins the long way when the fight calls for it.

The two title fights show both versions. Against Korkmaz at Oktagon 80 on 22 Nov 2025 the fight went the full 5:00 of round five and Legierski took the decision. Against Aksu at Oktagon 90 on 20 Jun 2026 it was over before round two.

Legierski's last five fights

Date	Opponent	Result	Method	Round
20 Jun 2026	Gökhan Aksu	Win	TKO	1
22 Nov 2025	Attila Korkmaz	Win	Decision	5
21 Sep 2024	Losene Keita	Loss	Decision	3
8 Jun 2024	Akonne Wanliss	Win	Decision	3
2 Mar 2024	Matouš Kohout	Win	Submission	1

Read from the bottom, it is a submission, a decision, a defeat and then two title wins by completely different routes. Two of the five ended in round one, the Kohout submission at the start of that run and the Aksu stoppage at the end of it.

Widen the window to the eight fights since July 2022 and the picture holds: seven wins, one loss, and the loss was a decision. Nobody has stopped Legierski in that stretch, which matters for a champion about to face an opponent with Buchinger's experience.

Next fight: Ivan Buchinger in Třinec

Oktagon 98: Legierski vs. Buchinger is booked for 21 Nov 2026 in Třinec, Czech Republic. The lightweight title is on the line, and the fight is the main event.

On paper it is a 30-year-old champion with 14 wins against an opponent with a 46-10-0 record. Legierski has shown that he can win the long way and the short way. What the main event will show is which of those two versions turns up against someone who has already been through a lot of fights.
