Nico Carrillo Takes Over ONE Featherweight Muay Thai Title

Tawanchai’s Title Exit and Injury

After a dominant run that included defending the belt multiple times, Tawanchai PK Saenchai has officially stepped down from the ONE Featherweight Muay Thai crown. The 27‑year‑old, who trains with the PK Saenchai Muaythaigym, first claimed the title at ONE 161 in 2022 with a five‑round decision over Petchmorakot. His reign featured victories over Jamal Yusupov, Superbon (twice) and a dual‑sport win against “Smokin’” Jo Nattawut, building a record of 10‑3 inside the organization. That streak ended abruptly in December 2025 when a 52‑second calf kick from Liu “Spirit Dragon” Mengyang forced him out and required surgery.

Carrillo’s Ascent to Undisputed King

With Tawanchai’s departure, the division promoter moved quickly to elevate Nico “King of the North” Carrillo from interim champion to undisputed titleholder. The 27‑year‑old fighter, sporting a career ledger of 29 wins and 4 losses, captured the interim belt at ONE Fight Night 40 by out‑working Shadow Mavinn. His climb has been marked by relentless finishing instinct and a growing reputation as a top contender in the featherweight ranks. Now he carries the full title and the weight of expectation for the division.

Looking Ahead: Kickboxing and Double‑Sport Ambitions

Despite the new champion’s immediate focus, the organization has already scheduled his next step: a kickboxing bout against Chinese prospect Zhou Jiaqiang at ONE Fight Night 46 on August 14 in Bangkok’s Lumpinee Stadium. This cross‑discipline fight highlights the growing trend of athletes adding kickboxing gold to their Muay Thai accolades. Carrillo’s ultimate goal is to become one of the rare ONE double‑sport champions, a club that currently includes a handful of elite fighters.
