The start of May will be grand, as ONE Championship is set to deliver an action-packed event. The blockbuster ONE Fight Night 31 will air live from the legendary Lumpinee Stadium in Bangkok.
On 3 May, the event will feature some of the greatest martial artists across MMA, Muay Thai, and submission grappling. The main attraction of the show will be a grudge match between two generational Thai superstars.

Third-ranked flyweight Muay Thai contender Kongthoranee Sor Sommai will aim to defeat the legendary Nong-O Hama in convincing fashion in their rematch of February 2025. The last time they fought, the match went in Kongthoranee's favour by a narrow margin.
Now, the former ONE Bantamweight Muay Thai World Champion will be eager to defeat his young compatriot and kickstart his winning run in the flyweight division. With 11 victories each under their belts in ONE, this is sure to be a barnburner.
In the co-main event, two of the world's best pound-for-pound Brazilian Jiu-Jitsu superstars will take centre stage for the World Championship bout. ONE Welterweight Submission Grappling World Champion Tye Ruotolo will defend his crown against his former rival Dante Leon.
Ruotolo and Leon have fought twice outside ONE, with the score tied at 1-1. Neither fighter has lost a bout in ONE Championship. This will be a highly technical matchup where anything can happen.
Meanwhile, an epic welterweight MMA contest between Zebaztian Kadestam and Isi Fitikefu could decide the next challenger. After a brief retirement, British sensation Liam Nolan returns to the ring to face the Iranian debutant Abolfazl Alipourandi.
