KSW 118: Kuberski vs. Michalski Headlines Two-Title Night in Kalisz

KSW 118 goes down on Saturday, 16 May 2026, at Arena Kalisz in Kalisz, Poland, with two championship fights topping a nine-bout MMA card. The event will stream live worldwide on KSWTV at 12:00 PM ET / 5:00 PM BST, giving fans outside Poland a full slate of action from start to finish.

Main Event

The main event crowns an interim middleweight champion as Piotr Kuberski faces Michał Michalski. Kuberski enters with a strong 17-1 record, while Michalski brings a 14-5 slate into one of the most important fights of his career.

This matchup has real significance for the division, with both men getting a chance to stake a claim in KSW’s middleweight picture. Kuberski’s consistency makes him a dangerous favorite on paper, but Michalski has the experience to turn this into a hard, tactical fight.

Co-Main Event

The co-main event features Wiktoria Czyżewska and Sara Luzar Smajić for the inaugural bantamweight championship. Czyżewska comes in at 7-1, while Smajić enters with a 6-3 record, setting up a title fight that could help define the division’s future.

A first champion always gives a weight class an added sense of urgency, and this bout should carry that energy. Both fighters have the chance to leave Kalisz with a new belt and a major career boost.

Big Matchups

The rest of the main card is packed with proven names and competitive matchups. Valeriu Mircea meets Roman Szymański at lightweight, while Marian Ziółkowski faces Aymard Guih in another 155-pound contest.

Two unbeaten welterweights, Adam Masaev and Michał Hir, also clash in a fight that could produce one of the night’s most intriguing storylines. Add in Dawid Kasperski vs. Aleksander Winiarski at light heavyweight and Konrad Rusiński vs. Tagir Machmudov at welterweight, and the card has depth across multiple divisions.

Prelims To Watch

The free preliminary portion, simulcast on YouTube, includes Michał Dreczkowski vs. Cedric Lushima at light heavyweight and Steven Krt vs. Borys Kolasiński at welterweight. That gives fans an accessible entry point before the main card begins.

KSW has built a reputation for strong matchmaking and competitive domestic cards, and KSW 118 fits that model well. With two titles at stake and several fighters trying to climb the ladder, it has the feel of a meaningful night for the promotion.

What To Expect

KSW 118 looks like a card built around stakes, not just names. The interim middleweight title and the inaugural bantamweight belt give the event real importance, while the supporting bouts offer a solid mix of prospects, veterans, and stylistically interesting fights.
