ONE Championship has added two MMA bouts to ONE Fight Night 50, the promotion’s final U.S. primetime event of 2026. Both fights are scheduled for December 18 at Lumpinee Stadium in Bangkok, Thailand.
In a lightweight matchup, ONE Lightweight Submission Grappling World Champion Kade Ruotolo will face former divisional champion Ok Rae Yoon. Ruotolo, 23, is 4-0 in MMA, with all four wins coming by finish.
Ruotolo last fought Hiroyuki Tetsuka, whom he knocked out. Ok Rae Yoon won the ONE lightweight MMA title by defeating Christian Lee. He brings a 17-6 record into the bout and is coming off two consecutive losses.
Swiss fighter Maurice Abevi will meet Turkish contender Dzhabir Dzhabrailov in a welterweight bout. Abevi, 27, has won three fights in a row and has a 9-1 professional record, with eight victories by finish.
Dzhabrailov, 21, is unbeaten at 7-0, with every win coming by finish. In his most recent bout, he recovered after being dropped by Chase Mann and went on to claim his fifth consecutive first-round finish.
Two-division ONE MMA World Champion Christian Lee is due to defend his lightweight title against Tye Ruotolo, Kade’s twin brother and ONE Welterweight Submission Grappling World Champion, at The Inner Circle 37 on November 6. ONE says a major win on December 18 could move any of the four contenders closer to a title shot.
