ONE Championship announces Sinsamut Klinmee as Nieky Holzken's opponent at ONE X

Nieky Holzken is ready to fight anyone. There’s no better proof than his fight at ONE Championship's 10-year anniversary show, ONE X.

Holzken was originally announced to fight Islam Murtazaev at the 10-year anniversary showcase, but the fight ultimately fell through. ‘The Natural’ was eager to get back in action, though, and graciously accepted the challenge of anyone willing to step in the circle with him.

Just days before the event, ONE Championship revealed that Holzken will be facing off against Sinsamut Klinmee.

Sinsamut is a product of Venum Training Camp Thailand, where he hones his skills alongside ONE stars Mehdi Zatout, Samy Sana and former ONE bantamweight kickboxing world champion Alaverdi Ramazanov.

With 78 victories in various competitions all over the world, the 25-year-old will now look to make an immediate impact on the global stage of ONE Championship by scoring a huge upset over the Dutch icon.

Their match takes place at ONE X: Part I, which kicks off at 1:00 PM SGT/5:00 AM ET.
