Kongthoranee Sor Sommai needs to stop the bleeding. The three-time Rajadamnern Stadium Muay Thai World Champion has watched his momentum evaporate across consecutive defeats to Nong-O Hama and Aslamjon Ortikov, yet his January 24 collision with perfect Russian prospect Asadula Imangazaliev at ONE Fight Night 39 on Prime Video could offer redemption — or confirms his slide from elite contention inside Bangkok’s Lumpinee Stadium broadcasting live in U.S. primetime.

The Thai cerebral technician’s 72-18 career record includes 11 ONE Championship victories built on counter-striking precision that once carried him through a seven-bout Friday Fights winning streak. Those performances, culminating in his majority decision over Jaosuayai Mor Krungthepthonburi that earned his six-figure contract, showcased the razor-sharp timing that later shocked the world when he defeated former bantamweight champion Nong-O Hama via split decision at ONE Fight Night 28 this past February.

That upset represented Kongthoranee’s ceiling, yet his floor arrived quickly through the rematch loss to Nong-O followed by a defeat to Aslamjon Ortikov. The fourth-ranked flyweight now faces a 22-year-old destroyer who’s never tasted defeat across 10 professional fights, where Imangazaliev’s 6-0 ONE Friday Fights record includes five stoppages through flashy kicks and spinning attacks that overwhelm opponents from angles they can’t anticipate.

Seven-time Muay Thai World Champion Panpayak Jitmuangnon discovered that reality when Imangazaliev’s thunderous head kick shut off his lights at ONE Friday Fights 122 in August. That finish earned the Russian his six-figure contract and positioned him to steal Kongthoranee’s top-five ranking through a performance that could expose whether the Thai veteran still belongs among the division’s elite or if his recent struggles signal deeper decline.

The co-main event delivers another Thailand-versus-Russia collision where rankings hang in the balance. Rambolek Chor Ajalaboon meets Abdulla Dayakaev after their ONE Fight Night 37 bout collapsed last month when the Russian’s staph infection forced withdrawal. Both bantamweights carry four-fight winning streaks built on devastating knockout power that’s positioned them at numbers four and five in the divisional rankings.

Rambolek’s evolution since joining Superbon Training Camp has transformed the 22-year-old Thai striker — ONE Friday Fights’ first six-figure contract winner — into a legitimate knockout artist. His back-to-back finishes of Parham Gheirati at ONE Fight Night 29 in March and Dmitrii Kovtun at ONE Fight Night 35 six months later demonstrated power that’s always existed but now arrives with technical precision learned from world-class training partners.

Dayakaev brings equally dangerous finishing ability through his 15-2 career record featuring eight ONE Championship victories. The 23-year-old Russian’s speed, precision, and destructive power created four straight stoppages that announced his arrival among bantamweight’s most feared finishers. His U.S. primetime debut at ONE Fight Night 31 in May showcased championship mettle when he survived Saemapetch Fairtex’s early knockdown before powering ahead for come-from-behind TKO victory.

Yet his last performance proved even more terrifying. Moving up to featherweight against Nontachai Jitmuangnon at ONE Fight Night 33 in July, Dayakaev authored the division’s fastest knockout by obliterating his opponent in just 24 seconds — a statement that confirmed his finishing instinct transcends weight classes.
