ONE Championship has added two MMA bouts to ONE Fight Night 50, headlined by a lightweight matchup between Kade Ruotolo and former champion Ok Rae Yoon, according to the promotion's announcement. The event streams on Prime Video from Lumpinee Stadium in Bangkok on Dec. 18.
Ruotolo, ONE's lightweight submission grappling world champion, is unbeaten in MMA at 4-0 with a 100 percent finishing rate, a record independently confirmed by his Wikipedia page, which lists his wins by date: Blake Cooper in June 2024, Ahmed Mujtaba that November, Nicolas Alejandro Vigna in February 2025 and Hiroyuki Tetsuka, his first knockout, this past May. Ok Rae Yoon previously held the lightweight MMA title after beating Christian Lee for it and was named ONE's 2021 Male MMA Fighter of the Year, but he enters this bout at 17-6 and on a two-fight losing streak.
The card's other new addition pairs two unbeaten-caliber prospects at welterweight. Switzerland's Maurice Abevi, 9-1 with eight wins by finish, has won three straight since a narrow defeat in his ONE debut. Turkey's Dzhabir Dzhabrailov is 7-0 with a wrestling base and five consecutive first-round finishes, most recently rallying from an early knockdown to stop Chase Mann.
ONE frames both bouts as building toward a future title opportunity, timed around a bigger date on the calendar. Christian Lee, who holds both the lightweight and welterweight MMA titles, defends his lightweight belt against Tye Ruotolo, Kade's twin brother, at The Inner Circle 37 on Nov. 6. A win for any of the four fighters added to the December card would put them in the conversation for a shot at one of Lee's titles once that fight is settled.
