Shadow Singha Mawynn enters this championship bout with a Muay Thai professional record of 83 wins, 24 losses, 1 draw, and 1 no contest. The 25-year-old Bangkok resident captured the Rajadamnern Stadium Welterweight title in 2022 and won the Rajadamnern World Series tournament the same year.
His ONE Championship tenure began with a loss in February 2024, but he responded with five consecutive victories over notable opposition including former World Title challenger Jimmy Vienot and seven-time World Champion Sitthichai Sitsongpeenong. Shadow secured his six-figure contract with a knockout of Hassan Vahdanirad at ONE Friday Fights 100 in March 2025. His most recent win came via spinning backfist against WBC Muay Thai World Champion Bampara Kouyate in September 2025.
Nico Carrillo brings a 22-2 professional record into this contest. The 27-year-old Glasgow native, known as “King of the North,” joined ONE Championship in April 2023 and immediately made an impact with a third-round TKO of Furkan Karabag.
Carrillo then dropped to bantamweight, where he earned Performance of the Night bonuses for knockouts against Muangthai PK Saenchai, Nong-O Hama, and Saemapetch Fairtex. His bantamweight title aspirations ended at ONE 170 in January 2025 when Nabil Anane stopped him in the first round.
Following that setback, Carrillo returned to featherweight, where he has remained undefeated. He knocked out Sitthichai Sitsongpeenong in April 2025 and finished American contender Luke Lessei in November 2025.
Whoever wins at Lumpinee Stadium will earn a future unification bout against Tawanchai once he recovers from injury. For Carrillo, this represents his second opportunity at ONE gold after his bantamweight title bid fell short. For Shadow, a victory would validate his ascent from regional circuits in Tak province to the global stage and complete his journey from poverty to World Champion.
