Background
As a new season blooms, so does the promise of glory – and on Friday, April 10, that promise will be tested when the world’s largest martial arts organization returns with ONE Fight Night 42: Mann vs. Dzhabrailov, broadcasting live in U.S. primetime from Bangkok’s Lumpinee Stadium.
In the headline attraction, a pair of undefeated warriors will throw down in the ring, and whoever emerges victorious could break into the ONE Welterweight MMA World Title conversation.
Chase Mann has steamrolled the competition with his heavy fists, grappling prowess, and sheer physical dominance – and he shows no signs of slowing down. Another outstanding performance may be enough to secure the 29-year-old American powerhouse a shot at Christian Lee’s coveted welterweight belt.
But 21-year-old Turkish juggernaut Dzhabir Dzhabrailov may be the most dangerous competitor he has ever faced, a true demolition man who has finished every single opponent and left a trail of destruction in his wake. If he can add the “Mannimal” to his list of victims, then he could potentially vie for the welterweight crown next.
Also, living legend Sam-A Gaiyanghadao makes his highly anticipated return in the co-main event. At 42 years old, the former multiple-time ONE World Champion is embarking on one final run at glory – and with two straight wins fueling his momentum, no one should dare count him out.
Standing in his path is 28-year-old Moroccan knockout artist Elmehdi El Jamari, a lethal boxer who has made a habit of putting his opponents’ lights out. At ONE Fight Night 42, he will be looking to destroy the icon’s fairytale comeback story in their strawweight Muay Thai showdown.
A ONE Lightweight Kickboxing World Championship bout for the vacant title between former champion (also a current ONE Lightweight Muay Thai World Champion) Regian Eersel and Rungrawee Sitsongpeenong was scheduled to headline the event.But the bout was moved to ONE Friday Fights 150 instead, Therefore, a Welterweight bout between Chase Mann and Dzhabir Dzhabrailov will headline the event.[
