ONE ChampionshipNico Carrillo has been elevated from interim titleholder to undisputed ONE Featherweight Muay Thai World Champion after Tawanchai PK Saenchai officially vacated the title to continue rehabbing a serious leg injury. Carrillo now returns to action against Chinese newcomer Zhou Jiaqiang in a kickboxing bout at ONE Fight Night 46 on Friday, August 14. “Tawanchai broke his leg a couple of months before Shadow, and I fought for the interim belt, which, in my opinion, should have been made for the undisputed belt anyway. Carrillo has scored knockouts in six of his seven promotional victories, including a finish of former ONE Bantamweight Muay Thai World Champion Nong-O Hama. A win over Zhou would put Nico Carrillo on course to chase two-sport World Champion status, adding kickboxing hardware to a featherweight Muay Thai throne he now holds outright.
