What happened: Johan Estupinan is set to meet Akif Guluzada this Friday, June 26, at ONE Fight Night 44, airing on Prime Video at 9 PM ET. The card streams live in the U.S. and Canada on Prime, on Sky Sports in the U.K. and Ireland, and via TV broadcast in more than 195 countries. Estupinan enters off a knockout win over Zakaria El Jamari.

Why it matters: The matchup pairs two aggressive strikers and carries momentum stakes for both men inside ONE Championship's striking ranks. A statement performance would strengthen Estupinan's standing as he builds on his recent finish, while Guluzada looks to assert himself against a surging opponent.

What to watch: Watch whether Estupinan's knockout power carries over against Guluzada when the two meet Friday. The result should clarify where each fighter sits in the divisional pecking order heading into the back half of 2026.
