Regian Eersel headlines The Inner Circle on April 10 against Rungrawee in ONE Lightweight Kickboxing World Title fight

ONE Championship returns to Lumpinee Stadium in Bangkok, Thailand on Friday, April 10, with another exclusive card for members of The Inner Circle. Five bouts are on the card, headlined by a World Title fight that puts one of the most decorated fighters in ONE history against one of Thailand’s sharpest southpaws.

Regian “The Immortal” Eersel faces Rungrawee “Legatron” Sitsongpeenong for the vacant ONE Lightweight Kickboxing World Title in the main event.

Eersel, 33, has held the ONE Lightweight Kickboxing World Title six times and the ONE Lightweight Muay Thai World Title four times — 10 ONE World Championship reigns in total. He arrives on a three-fight winning streak, including a first-round knockout of George Jarvis at ONE Fight Night 34.

Rungrawee carries a 158-48 record into the biggest fight of his career. The 30-year-old Sitsongpeenong southpaw punishes opponents with a sharp straight left and devastating left low kicks, and has lost just once in 18 kickboxing bouts. He earned his nickname “Legatron” for exactly the weapons he plans to bring to Bangkok on April 10.

Mohammed meets Rittidet in The Inner Circle co-main event

The co-main event is a strawweight Muay Thai clash between two Rajadamnern Stadium World Champions. Isaac “Petnueng” Mohammed is a 20-year-old French-Algerian fighter trained at Petch Muay Thai Gym. He brings a nine-fight winning streak and a relentless style built on elbows, body kicks, and forward pressure. He claimed the Rajadamnern Stadium title at just 17 and earned Channel 7’s Fans’ Favorite Fighter award in 2025.

Across from him stands Rittidet Lukjaoporongtom, a 21-year-old southpaw from Buriram who claimed his Rajadamnern Stadium title at 15. The Kiatsongrit Muay Thai Gym fighter works behind a sharp straight left and left body kick, using quick combinations and feints to create his angles. Two world-class Muay Thai minds, two completely contrasting styles.

Rounding out the card, Elies Abdelali faces Hicham Zerouali in featherweight Muay Thai. Kaokarat Sor Tienpo meets Logan Chan in bantamweight Muay Thai. Hero Marco Manguray takes on Kota Abe in a lightweight MMA clash.
