ONE 167's main event saw One Championship featherweight muay thai champion Tawanchai P.K. Saenchai successfully defend his belt against a tough challenger in Nattawut Somkhun.
Saenchai wasted no time establishing himself as a force to be reckoned with by delivering punishing leg kicks and sharp elbows to Somkhun. Standing his ground, the challenger would find his footing and have success with combinations when Saenchai would lower his output, with Somkhun taking over the third and fourth rounds. However, the champion showed his resolve in the final three minutes, as it was a back-and-forth battle that saw both men have their moments.
