Isannuea Warns Jack's Iron Chin Will Make War At ONE Friday Fights 177

Isannuea Sor Sasiwat has spent years studying Jack Siatanyokkrok PK's fights, and his scouting report points to one conclusion: this is going to be a slugfest.

The 22-year-old Thai knockout artist faces Jack in the bantamweight Muay Thai headliner of ONE Friday Fights 177 on November 6 at Lumpinee Stadium in Bangkok. Isannuea moves up from flyweight for the first time, having grown out of the lower division, though he intends to return after this bout. He holds a perfect finishing rate inside ONE among his wins, but dropped a decision to Ubaid Hussain in August.

Isannuea has tracked Jack's career extensively, watching both his five-round traditional stadium bouts and his appearances in smaller gloves. What stands out most is not power or technique but pure toughness. "He's got an iron chin and insane toughness," Isannuea told BJPenn.com, describing the 31-year-old as a pressure fighter who keeps coming forward.

Jack brings 72 career wins into Friday's clash. He posted a 2-1 record on the weekly series in 2023, with both victories ending inside the opening round. Since joining PK Saenchai Muaythaigym this past July, he has built momentum heading into the matchup. Jack said he plans to open behind his hands before rotating through kicks, knees and elbows as the fight wears on.

Jack believes he can weather an early storm and take control in the later rounds. He said his preparation covered every weapon and promised full commitment from the opening bell. Isannuea's frame has outgrown flyweight for now, but he expects to return to 125 pounds once this bantamweight test is complete.
