Rambolek Chor Ajalaboon makes the first defense of his ONE Bantamweight Muay Thai World Title this Friday, September 11, but the most emotionally charged moment of the night belongs to a fighter walking away from the sport for good.
The Superbon Training Camp product defends his crown against Yod-IQ Or Pimolsri in the main event of The Inner Circle 30, streaming live for members from Bangkok’s Lumpinee Stadium.

Rambolek claimed the title by dethroning former champion Nabil Anane this past March, ending one of the most formidable unbeaten runs in the division’s history. He earned that shot with a stoppage of Abdulla Dayakaev, a fighter who had finished his previous four opponents by knockout, and stepped away into monkhood for a period of reflection before returning with his title in hand.
Yod-IQ arrives on a 10-fight winning streak built alongside mentor and former ONE Featherweight Muay Thai World Champion Tawanchai PK Saenchai. His resume includes a US$100,000 contract-clinching win over Alexey Balyko and a recent decision over Kiamran Nabati that drew comparisons to the platform’s best performances this year.
The co-main event closes the book on one of Thai Muay Thai’s fiercest rivalries. Seksan Or Kwanmuang fights for the final time against Muangthai PK Saenchai, the man who handed him the only loss of their long series with a unanimous decision this past June.

Seksan built his legend across decades, capturing Muay Thai World Titles at both Rajadamnern and Lumpinee Stadium before a six-fight bonus streak in ONE Championship turned him into a global name. His retirement bout against the fighter who finally solved him adds a poetic final chapter to a career defined by rivalries, closing the loop on a series that has produced some of the weekly platform’s most memorable action.
Three additional bouts round out the card, including a strawweight matchup between Freddie Haggerty and Rungruanglek TN Muaythai.
Whether Seksan closes his career with one last statement or Muangthai has the final word, September 11 promises to deliver both championship stakes and genuine sentiment in equal measure.
