The Tipsport Gamechanger middleweight tournament was in full swing at Saturday’s Oktagon 70, with four opening round bouts plus a tournament alternate fight.
Those four opening round fights comprised the bulk of the main card, with Samuel ‘Pirát’ Krištofič and Dominik Humburger headlining the show. Earlier in the night, meanwhile, Czech welterweight Andrej Kalašnik faced off against former title challenger Máté Kertész, looking to make his own run at gold.
The featured fight of the preliminary card, meanwhile, found champ Mallory Martin defending her women’s strawweight championship opposite Eva Dourthe. American Martin, an Invicta FC and UFC alum, had won three fights to start her run with Oktagon MMA and captured the promotion’s 115lb title opposite Katharina Dalisda back in October.
