Description

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: Eersel vs. Rungrawee, broadcasting live in U.S. primetime from Bangkok’s Lumpinee Stadium.

In the headline attraction, a pair of elite strikers will stand toe-to-toe with the vacant ONE Lightweight Kickboxing World Title hanging in the balance.

Regian “The Immortal” Eersel has been one of the most dominant fighters over the past decade, having fearlessly accepted every challenge that has been thrown at him and demolishing any opponent who crossed him in the ring. Now, the reigning ONE Lightweight Muay Thai World Champion wants to reclaim the vacant belt he used to own and regain his status as a two-sport king.

But Rungrawee “Legatron” Sitsongpeenong has worked toward this moment his entire life, and he refuses to let it slip through his hands. The Thai star has spent years harnessing his power and refining his skills, leading him to a staggering 158 career victories. Rungrawee brings more experience into this battle and will stop at nothing to claim the richest prize in the sport in front of his hometown crowd.
