OKTAGON 77 arrives in Bratislava on October 4, 2025, promising one of the promotion’s most stacked cards of the year. Taking place inside Tipos Arena, the event is headlined by a pivotal middleweight clash in the €1 million Tipsport Gamechanger middleweight tournament between Kerim Engizek and Dominik Humburger. With Engizek sitting at the top of the German middleweight rankings and Humburger pushing from Eastern Europe’s elite, this main event could decide the future shape of the division.
Also in the European MMA Champions League tournament, Krzysztof Jotko takes on Hojat Khajevand. Jotko, a seasoned veteran with extensive UFC experience, brings a wealth of big-fight know-how, while Khajevand’s wrestling base and sharp striking make him one of the tournament’s most dangerous dark horses. Their battle of styles promises to be a fascinating contest of patience and pressure.
Local hero Ivan Buchinger also returns to the cage to face Ireland’s Richie Smullen. Buchinger, a Slovak legend and former two-division champion, will enjoy thunderous support from the home crowd as he looks to show he can still perform at the highest level. Smullen, meanwhile, has built a reputation for durability and relentless pace, making this a fight with both high emotion and high stakes.
For fans craving fireworks, Vlasto Čepo vs. Daniel Schwindt is being billed as a “war of the hardest fists.” Both men prefer to settle matters on the feet, and few expect this one to go the distance. Add to that a reserve match in the Tipsport Gamechanger between Samuel “Pirát” Krištofič and Jaime Cordero, and the Bratislava crowd is guaranteed an action-packed night.
Ultimately, OKTAGON 77 is about more than just individual matchups. It is a night where rising stars try to dethrone veterans, where reputations and rankings hang in the balance, and where the roar of the Slovak crowd could make all the difference. With semifinal places and a life-changing prize fund on the line, every fighter who steps into the cage on October 4 will be chasing not only victory, but legacy.
