Lightweight Muay Thai king Regian Eersel defends his throne against surging George Jarvis in August

Regian Eersel is back for another tough test in his incredible ONE Championship career. The reigning ONE lightweight Muay Thai world champion dons small gloves again to defend his throne against the surging George Jarvis in the main event of ONE Fight Night 34 on August 1, U.S. primetime, at the historic Lumpinee Stadium.

ONE Championship announced the Bangkok banger on its social media channels and official website. The promotion posted:

"Watch the THRONE 👑 Surinamese superstar Regian Eersel defends the ONE Lightweight Muay Thai World Title against surging British striker George Jarvis in the main event of ONE Fight Night 34 on @primevideo on August 1! Will 'G-Unit' usurp 'The Immortal'? @koolhydraat @georgejarv1."

Regian Eersel is undoubtedly one of the greatest strikers of his generation and holds a stellar 12-1 record in his ONE Championship tenure.

'The Immortal' was a six-time ONE lightweight kickboxing world title, and he held the strap on two occasions from May 2019 to April 2024 and from October 2024 through April 2025.

His second reign with the kickboxing gold could've gone longer, but he was stripped after failing to make weight for his trilogy fight against the only man to beat him in ONE Championship, Alexis Nicolas.

In October 2022, Eersel captured the inaugural ONE lightweight Muay Thai world title and has since defended that strap two times against Sinsamut Klinmee and Dmitry Menshikov. Jarvis, meanwhile, is one of the United Kingdom's fastest-rising stars.

'G-Unit' is 27-4 in his career, and rides a four-fight winning streak ahead of his world title challenge against Eersel.

Jarvis chalked up impressive wins over Mustafa Al Tekreeti, Ricardo Bravo, Rungrawee Sitsongpeenong, and Mouhcine Chafi en route to the biggest fight of his career.

ONE Fight Night 34 is available live and free to all Prime Video subscribers in the United States and Canada.

Regian Eersel leaves it up to ONE Championship for his next kickboxing contender

Regian Eersel is hellbent on recapturing the vacant ONE lightweight kickboxing world title, but he'll leave it to ONE Championship to decide his next potential matchup.

The Surinamese-Dutch superstar was stripped of the division's throne when he missed weight in his supposed world title defense over Alexis Nicolas at ONE Fight Night 30 in April.

Eersel ultimately beat Nicolas via majority decision in their trilogy and said it's up to ONE Championship who he should face next.

He said in his interview with the Bangkok Post:

"In kickboxing right now, I don't see any name."
