The confirmed MMA result

ONE Championship’s official results list Ryoto Nishiyama defeating Geun Ho Son by knockout at 4:36 of round one in their flyweight MMA bout at Lumpinee Stadium in Bangkok on August 28.

Why the event desk changes

Son–Nishiyama was the only contest on ONE Friday Fights 168 classified as MMA. Fight Atlas has therefore closed that one-bout MMA event card without converting the promotion’s eight Muay Thai and kickboxing results into professional MMA records.

Neither fighter currently has a complete verified Fight Atlas career profile. The result is recorded on the event and news desks, while fighter-record integration remains withheld until a complete public fight-record source can be reconciled for both athletes.
