ONE Championship returns to the hallowed grounds of Lumpinee Stadium in Bangkok, Thailand, on June 12 as The Inner Circle 18 and ONE Friday Fights 158 deliver another night of world-class striking action live in Asia primetime.

Featuring international competitors battling under Muay Thai, kickboxing, and MMA rules, both cards carry serious stakes, with a life-changing US$100,000 ONE Championship contract on the line for the most impressive performers.

Exclusively for members of The Inner Circle, flyweight Muay Thai headline duty falls to Tomyamkoong Bhumjaithai, who rides a three-fight winning streak into a dangerous matchup with Azerbaijani brawler Anar Mammadov. The PK Saenchai Muaythaigym product is one strong performance away from a six-figure contract, but Mammadov’s experience and punishing power make him a genuine threat to derail those plans. In the co-main event, Rambong Sor Therapat meets the hard-charging Sornsueknoi FA Group in a flyweight Muay Thai collision between two battle-tested competitors with plenty left to prove.

In the main event of ONE Friday Fights 158, knockout artist Maisangkum Sor Yingcharoenkarnchang puts his explosive left hook and iron will to the test against surging Laotian pressure fighter Petnamkhong Sor Maneekhot. Riding a two-fight winning streak with a nation behind him, Petnamkhong isn’t just fighting for a contract, he’s fighting for something bigger. Before that, Russian technician Mamuka Usubyan squares off with French-Algerian debutant Enzo Kartoum in a featherweight kickboxing co-main event.

So, mark your calendar, put a reminder in your phone, and find out how you can watch The Inner Circle 18 and ONE Friday Fights 158 live on June 12 in more than 190 countries around the globe!
