On April 11, 2026, in Bangkok, Thailand, ONE Championship presented a thrilling event at Lumpinee Stadium, highlighted by the welterweight MMA main event of ONE Fight Night 42: Mann vs. Dzhabrailov.
The undefeated Turkish contender, Dzhabir Dzhabrailov, delivered a memorable first-round knockout against Chase “Mannimal” Mann. This victory handed Mann, an American fighter, the first defeat of his professional career.
Mann started the bout aggressively, pursuing a takedown and controlling the initial pace. He landed the first significant blow, a sharp right hook that momentarily put Dzhabrailov on the canvas. However, the 21-year-old Turkish prodigy demonstrated remarkable resilience, quickly recovering and re-engaging in the fight.
Following a rapid exchange of strikes on their feet, Dzhabrailov skillfully maneuvered Mann into a corner. From there, the Turkish fighter unleashed a powerful left hook that connected cleanly, immediately sending the Arkansas native to the mat. Two subsequent ground strikes from Dzhabrailov sealed the emphatic, highlight-reel victory.
In the co-main event, former multiple-time ONE World Champion Sam-A Gaiyanghadao put on a classic performance against Morocco’s Elmehdi “The Sniper” El Jamari. Despite facing a significant scare, the Thai legend secured three knockdowns in the second round, ultimately winning by technical knockout.
Sam-A adopted a patient approach in the first round, looking for counter-opportunities while El Jamari pressed forward confidently. “The Sniper” found early success with a couple of effective uppercuts, forcing the veteran Thai fighter onto the defensive.
The second round saw a dramatic shift in momentum as Sam-A increased his offensive output, unleashing a series of dynamic striking combinations. A forceful left hook knocked El Jamari down, but he managed to beat the referee’s count. Shortly after, Sam-A landed a precise straight left, dropping his opponent for the second time.
In a surprising turn of events, El Jamari landed a left hook that sent Sam-A to the canvas, leaving the Thai icon visibly unsteady. While still recovering, Sam-A delivered a swift, fight-ending head kick that dropped “The Sniper” for the third time, prompting the referee to stop the contest.
