Saturday’s KSW 110 card was headlined by a familiar face in Andrzej Grzebyk, who was taking on Muslim Tulshaev in a catchweight main event – but he was far from the only recognizable name in action.
Polish-Canadian light heavyweight Mariusz Książkiewicz was also featured on the card, just two fights from the top of the marquee in fact. The Contender Series veteran had posted a 3-1 record since losing on DWCS in 2020, and had won a regional title by defeating Rafael Carvalho in his last outing.
Also adorning the KSW 110 card, UFC vet Rogerio Bontorin was making his KSW debut, looking to follow up on a 2023 victory under Japanese promotion RIZIN FF.
