Dzhabir Dzhabrailov Secures First-Round Knockout Against Chase Mann in Welterweight Showdown

On April 11, 2026, the Lumpinee Stadium in Bangkok, Thailand, hosted an electrifying ONE Championship event, ONE Fight Night 42, headlined by a highly anticipated welterweight MMA bout between two undefeated fighters.

The main event saw Turkish rising star Dzhabir Dzhabrailov achieve a spectacular first-round knockout victory over American contender Chase "Mannimal" Mann, marking the first professional loss for Mann.

Mann started aggressively, pursuing a takedown and controlling the initial pace. He landed the first significant blow, a sharp right hook that momentarily dropped Dzhabrailov. However, the 21-year-old Turkish fighter demonstrated remarkable resilience, quickly recovering and re-engaging.

Following a rapid exchange of strikes, Dzhabrailov strategically cornered Mann. He then landed a powerful left hook that immediately sent the Arkansas native to the canvas. Two subsequent hammerfists from Dzhabrailov sealed the emphatic, highlight-reel finish.

In the co-main event, the legendary former ONE World Champion Sam-A Gaiyanghadao showcased his enduring skill against Morocco's Elmehdi "The Sniper" El Jamari. Despite facing a moment of peril, the Thai icon secured a technical knockout win 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 the attack, finding early success with uppercuts that pushed Sam-A onto the defensive.

The tide turned dramatically in the second round as Sam-A switched gears, launching a series of dynamic striking combinations. A potent left hook knocked El Jamari down, though he managed to beat the referee's count. Moments later, a precise straight left from Sam-A sent El Jamari down for a second time.

In a sudden turn of events, El Jamari landed a left hook that sent Sam-A to the mat, leaving the Thai fighter visibly unsteady. Despite the adversity, Sam-A responded with a swift, fight-ending head kick that knocked "The Sniper" out cold, prompting the referee to stop the contest.
