Muay Thai’s competitive spirit took a hit with the recent lifetime ban imposed on Mahahin Petkiatpet by ONE Championship. This decision followed his second-round knockout loss to Dionatha Santos Tobias during ONE Friday Fights 89. The knockout raised eyebrows and sparked debates within the community, leading many to question whether the outcome was genuine or manipulated for personal gain.
The Ban
ONE Championship wasted no time addressing the issue. The organization’s swift lifetime ban reflected its zero-tolerance policy against unethical practices. Observers highlighted Mahahin’s questionable performance during the second round, where he appeared to offer minimal resistance.

His management team, Kiatpetch Promotions, stepped forward to address the fallout. Promoter Deer Kiatpetch issued a public apology, acknowledging the harm done to both the team’s reputation and the sport itself. He vowed to hold all fighters under his banner to higher standards moving forward.

In his statement, Kiatpetch urged his athletes to remain true to their craft, emphasizing the importance of integrity over shortcuts. “Let this be a lesson for everyone under my promotion,” he stated, signaling a stronger stance on professionalism within the sport.
The Shadow of Gambling Scandals
The incident reignited concerns about gambling’s influence in combat sports. Speculation swirled that Mahahin might have thrown the match to manipulate betting outcomes. While no conclusive evidence has surfaced, such allegations cast a long shadow over the fighter’s career.
Insiders noted that gambling scandals are not uncommon, with stars in the past allegedly placing bets against themselves. Such actions violate organizational codes and are punishable across the board. Kiatpetch echoed these concerns, underscoring the serious consequences of breaching ONE Championship’s contractual rules.Interestingly majority or sportsbooks stopped offering odds about ONE when ONE secretly aired pre-taped shows in 2020.
What’s Next for Mahahin?
For now, Mahahin’s career hangs in limbo. His training has been suspended indefinitely, and his team awaits further clarification from the fighter. While Kiatpetch has left the door open for an explanation, the path to redemption seems uncertain.
