Along with making official the first-ever ONE Championship men’s strawweight title fight, several changes have been made to the ONE: Warrior’s Quest event.

Set for May 22 from the Singapore Indoor Stadium in Singapore, the card features Shinya Aoki defending his lightweight title against Koji Ando.

Dejdamrong Sor Amnuaysirichoke battles Roy Doliguez for the 115-pound title in the co-main event, while Stephen Langdown faces A La Teng Hei Li and Ariel Sexton replaces Rafael Nunes for a lightweight scrap vs. Eddie Ng.

While Sor Amnuaysirichoke is just 4-0 in MMA, he sports a record of 282-65 in muay Thai and is a former world champion. All four of his ONE wins have been finishes, while Doliguez (6-1) is on a four-fight win streak and will be debuting with the Asian promotion.
