Dzhabir Dzhabrailov Scores First-Round KO Of Chase Mann In Battle Of Undefeated Welterweights

Bangkok, Thailand – April 11, 2026 – The Lumpinee Stadium was once again the stage for an electrifying martial arts spectacle as ONE Championship presented ONE Fight Night 42: Mann vs. Dzhabrailov.

In a highly anticipated welterweight MMA main event, the undefeated Turkish fighter Dzhabir Dzhabrailov delivered a breathtaking first-round knockout performance against Chase “Mannimal” Mann. This victory marks the first professional defeat for the American contender.

Mann began the fight aggressively, seeking a takedown and setting a brisk pace. He landed the first significant blow, a sharp right hook that sent Dzhabrailov to the canvas. However, the 21-year-old Turkish prodigy demonstrated remarkable resilience, quickly recovering and re-engaging in the bout.

Following a rapid exchange of strikes, Dzhabrailov skillfully maneuvered Mann into the corner of the ring. There, the Turkish fighter unleashed a powerful left hook that landed perfectly, instantly incapacitating the Arkansas native. Two subsequent hammerfists from Dzhabrailov sealed the emphatic, highlight-reel finish.

The co-main event featured a vintage performance from former multiple-time ONE World Champion Sam-A Gaiyanghadao against Morocco’s Elmehdi “The Sniper” El Jamari. Despite facing a significant scare, the Thai legend secured a technical knockout victory by scoring three knockdowns in the second round.

Sam-A adopted a patient approach in the first round, looking for counter-opportunities while El Jamari pressed forward confidently. “The Sniper” found success early, landing a couple of strong uppercuts that forced the veteran into a defensive posture.

The second round saw a dramatic shift in momentum as Sam-A increased his aggression, unleashing a series of dynamic striking combinations. A powerful left hook dropped El Jamari, who managed to beat the referee’s eight-count. Moments later, Sam-A landed a precise straight left, sending his opponent to the canvas for a second time.

In a stunning turn of events, El Jamari responded with a devastating left hook that sent Sam-A to the mat, leaving the Thai icon visibly shaken. While still recovering, Sam-A threw a lightning-fast head kick that knocked “The Sniper” down for the third and final time, prompting the referee to stop the contest.
