Urgent: "Tawanchai" has vacated the ONE Muay Thai World Championship, revealing the shocking reason behind the announcement.
On 21 July 2026, Tawanchai P.K. Saenchai Muaythai Gym announced he is relinquishing the ONE Muay Thai Featherweight World Championship due to ongoing recovery from injury.
ONE Championship, the world's leading martial arts organization, confirmed that Tawanchai P.K. Saenchai, the ONE Muay Thai Featherweight World Champion (145-155 lbs), has vacated the title to focus on fully recovering from his injury.
As a result, Nico Carrillo, the interim world champion from Scotland, has been officially promoted to full world champion.
This decision stems from a broken shin injury Tawanchai suffered at ONE Lumpinee 137 in December 2025, requiring a long recovery and preventing him from defending his title.
Known as the "Left Star," he chose to relinquish the title he held since September 2022 to allow the featherweight division to continue moving forward.
