Overview
- ONE Championship announced Tuesday that Tawanchai PK Saenchai has officially vacated the ONE Featherweight Muay Thai World Title while he continues rehabilitation from a leg injury.
- Nico Carrillo has been elevated from interim champion to undisputed ONE Featherweight Muay Thai World Champion after winning the interim belt earlier this year against Shadow Singha Mawynn.
- ONE has scheduled Carrillo to make his ONE kickboxing debut against Zhou Jiaqiang at ONE Fight Night 46 on August 14 at Lumpinee Stadium in Bangkok.
- Tawanchai’s absence follows a December 2025 kickboxing loss to Liu Mengyang that ended in a 52-second calf-kick finish and required surgery, and he remains in extended rehab.
- The promotion’s move clears the division to progress, hands stewardship to Carrillo, and creates a path for him to try for two-sport gold while Tawanchai would return as a challenger rather than a reigning champion.
