Full Card Revealed For The Inner Circle 31 On September 18

Nontachai Jitmuangnon punches Semih Sah Cindir at ONE Friday Fights 145

ONE Championship takes over Lumpinee Stadium in Bangkok, Thailand, on Friday, September 18, with a stacked bantamweight card for hardcore Muay Thai fans, and it streams live for members at live.onefc.com.

At The Inner Circle 31, a contracted Russian powerhouse looks to bounce back against one of Thailand’s most technically gifted young fighters in the main event, while two Muay Thai veterans slide into the kickboxing realm for the first time in their ONE careers.

In the main event, Kiamran Nabati faces Nontachai Jitmuangnon in a bantamweight Muay Thai bout that won’t go the distance.

Nabati built his name with one of the most destructive unbeaten runs the weekly platform has seen — a contract-earning first-round knockout of Suablack Tor Pran49 at ONE Friday Fights 68, followed by a unanimous decision over the legendary Nong-O Hama at ONE Friday Fights 81 that announced him as a genuine contender.

His most recent result — a split-decision loss to newly minted ONE Bantamweight Muay Thai World Champion Yod-IQ Or Pimolsri at ONE Friday Fights 155 — was his first professional defeat, and it has sharpened everything about how he approaches this fight.

Nontachai arrives on the back of the best result of his ONE career — a unanimous decision win over Felipe Lobo at ONE Fight Night 43 that followed a third-round TKO win over Semih Sah Cindir at ONE Friday Fights 145.

The Jitmuangnon Gym product won his ONE contract by taking the Road to ONE: Thailand tournament with a first-round knockout in the final. He is tall, technical, and capable of making even elite fighters look ordinary when he is at his best. A win over a contracted Russian powerhouse in his prime would be the defining result of his career so far.

In the co-main event, Yamin PK Saenchai takes on Alexey Balyko in bantamweight kickboxing.

Yamin’s time on the platform has been a tale of spectacular highs and sobering lows. He opened his ONE account with a third-round knockout of Zhang Jinhu at ONE Friday Fights 33 and a rapid 36-second TKO of Joachim Ouraghi at ONE Friday Fights 59, only to run into consecutive knockout losses — most recently a first-round finish by Sonrak Fairtex at ONE Friday Fights 130.

He needs a performance that recaptures his early form and restores his standing in the division.

Balyko is the durable Belarusian veteran who has tested some of the very best on the weekly platform over a long career at Lumpinee. He remains a genuine threat to anyone in the bantamweight division and is hungry for a result that puts him back in the conversation.
