One Championship recently released the full card for its upcoming event, One 157: Petchmorakot vs Vienot, scheduled for May 20 at the Singapore Indoor Stadium.
The One featherweight and strawweight Muay Thai world titles will be on the line in the main and co-main events.
One featherweight Muay Thai world champion Petchmorakot Petchyindee puts his gold on the line for the third time when he takes on French striking star Jimmy Vienot in the evening's headliner.
Vienot, who will be making his debut in the circle, is no stranger to world championship bouts, becoming one of the few non-Thais to win the prestigious Lumpinee Stadium world title in 2019.
He faces arguably his greatest challenge yet against Petchmorakot, who has defeated the likes of Pongsiri PK Saenchai, "The Boxing Computer" Yodsanklai Fairtex, and Liam "Hitman" Harrison.
Before that world title tussle takes place, One strawweight Muay Thai world champion Prajanchai PK Saenchai will step into the circle for the first time since snatching the strap off Sam-A Gaiyanghadao last year.
The Thai star looks to successfully defend his throne against Italian-Moroccan Joseph "The Hurricane" Lasiri, who has been on blistering form lately.
One 157 will also host the One flyweight Muay Thai world grand prix quarter-finals.
The opening round of action sees divisional kingpin Rodtang "The Iron Man" Jitmuangnon taking on Jacob Smith, Jonathan "The General" Haggerty against Walter Goncalves, Superlek Kiatmoo9 squaring off with Taiki "Silent Sniper" Naito, and Savvas "The Baby Face Killer" Michael fighting Amir Naseri.
Each star will seek to overcome their opponent and progress to the next round.
Muay Thai battles are set to dominate the card on May 20, but there's also an exciting mix of action away from "the art of eight limbs."
Teen Brazilian jiu-jitsu sensations the Ruotolo brothers will make their One debuts on the night, with Kade Ruotolo set to face Shinya Aoki and Tye Ruotolo coming up against Garry Tonon in submission grappling.
And in mixed martial arts, Muay Thai phenom Nat "Wondergirl" Jaroonsak will make her long-awaited MMA debut when she squares off against India's Zeba Bano.
