Dejdamrong Sor Amnuaysirichoke built his reputation on thrilling the masses across more than two decades as a combat sports star. How much he has left in the tank remains to be seen.

The three-division Lumpinee Stadium titlist will take on Banma Duoji in the One Championship “Battleground 3” main event on Friday at Singapore Indoor Stadium in Kallang, Singapore. Amnuaysirichoke, who made the transition to mixed martial arts in 2014, has rattled off three wins over his past five outings. He last appeared at One Championship “Reign of Dynasties” on Oct. 9, when he wound up on the wrong side of a split decision against Getu Hexi. Duoji, meanwhile, has won eight of his last nine bouts. However, he has not competed since he dropped a unanimous verdict to Andrey Marchenko under the Kunlun Fight banner on July 27, 2019.
