One man is fighting for a holiday. The other believes he is fighting for a second chance at the life he always wanted.
Isannuea Sor Sasiwat and Jack Siatanyokkrok PK meet in the bantamweight Muay Thai main event of ONE Friday Fights 177 on Friday, November 6, live in Asia primetime from Bangkok’s Lumpinee Stadium. Neither is built for a long night of point-fighting.

Isannuea, 22, has finished all four of his promotional victories but enters off an August loss to unbeaten Ubaid “Bad” Hussain. The Sit Erawan Gym and Sor Sasiwat athlete has treated that night as a lesson, and he is moving up to bantamweight for the first time as his body fills out.
“I felt a little bit bummed out about that loss. He hit me with a body hook [in the first round], and I just didn’t brace for it in time. But Ubaid has great skills. He’s really fast,” Isannuea said.
Jack, 31, returns to the weekly series for the first time since 2023, when he went 2-1 and scored first-round knockouts of Mardanglek Nakatawan in 82 seconds and Darkie Nokkhao KorMor11 in 45. He has since pushed his career win total to 72 on Thailand’s traditional stadium circuit.
He joined PK Saenchai Muaythaigym in July.

“I’ve still been actively fighting – mostly under the 5-round traditional fights. My performances have actually been pretty solid. I never stopped fighting. I kept the momentum going,” Jack said.
“Now, I’m super excited and honestly overjoyed to fight in ONE Championship again. It feels like getting a second chance at life because this is the ultimate dream and hope for both myself and my family.”
Isannuea is chasing the 51st win of his career, and he has a very specific reward in mind if it comes quickly.
“I’m definitely going to invite him into a firefight and drag him into a brawl. If the opportunity to finish him arrives, I’ll take it and end it fast. I don’t want to drag it to the final round,” he said.
“I’m going to put him away – no stalling. I’m gunning for the bonus, too. It’s the end of the year, so I want to grab that bonus and use it for a New Year’s trip!”
