Yodkhunpon Sitmonchai: Kun Khmer, K-1 and ONE chapters យ៉តឃុនផុន ស៊ីតមនឆៃ៖ គុនខ្មែរ ខ្សែក្រវាត់ K-1 និង ONE

English

One fighter across several names and rule systems

Yodkhunpon Sitmonchai is the Thai fighter also promoted as Yodkhunpon Weerasakreck, Yodkhunpon Mor Rattanbandit and Yodkhunpon Moothong Academy. K-1’s official profile identifies his birth date as 27 November 1994, his origin as Samut Sakhon and his height as 176 centimetres. He is not Yodkhunpon Sittraiphum, the earlier-generation fighter whose elbow reputation is widely discussed in Muay Thai history. The shared first ring name must never be used to merge those careers.

His relevance to Kun Khmer is direct: he faced Thoeun Theara at Kun Khmer All Star 3 in Phnom Penh on 25 March 2022. That Cambodian appearance sits within a wider career involving GLORY kickboxing, Thai Muay Thai events, K-1 and ONE Championship. Reading the sequence by discipline reveals a fighter repeatedly adapting to different competitive frameworks. It also prevents a K-1 championship from being incorrectly recorded as a Kun Khmer title.

Sitmonchai development and the first GLORY test

Sitmonchai’s own account associates him with the gym’s emerging talent and its international expansion. A 2014 GLORY interview captures him at an early stage of that overseas transition. After defeating Raz Sarkisjan by decision in Istanbul in April, he explained that unfamiliar rules had made him hesitate. Actions that felt natural in Muay Thai, including certain sweeps, were not available in the new setting. The value of the interview lies in that practical admission: technical experience did not remove the need to learn a different competition.

He also discussed adapting his preparation to a colder arena environment. That detail is more revealing than a generic statement that he trained hard. It shows the small operational adjustments that can affect an international debut even when the athlete already possesses substantial ring experience. The account belongs to 2014 and is not turned into a claim about every Thai gym’s current practice. It is the fighter’s recollection of a particular change in his working conditions.

Power with a specific technical basis

K-1’s profile later emphasised the threat of his left hook and the development of his punching during international competition. The 2024 tournament results provide concrete examples of early finishes, while the 2026 ONE recap describes a left-handed counter that ended his debut there. These sources support discussing his punching threat. They do not justify pretending to have measured his power scientifically or assigning a single unchanging stance to every exchange. The official K-1 listing describes his base stance as orthodox.

The Cambodian setback before later successes

The selected ledger records a first-round elbow stoppage loss to Theara in Phnom Penh in March 2022. Secondary sources disagree on the exact elapsed time, so it is omitted. The date, opponent, event and round provide the useful core of the result. For Cambodian readers, this establishes a real meeting with a fighter who would later obtain further international recognition. It should not be inflated into an unverified title contest or treated as proof that his subsequent career was predetermined by that one defeat.

The chronology instead illustrates how a professional career can continue across promotions after a setback. K-1’s official profile also lists TOPKING and MX Muay Xtreme championships at 70 kilograms. The 65-kilogram K-1 tournament was a different assignment. Each organisational title needs its own label because weight divisions and permitted techniques are not interchangeable. Historical achievements remain part of the biography without implying that every listed championship is still held.

Selected verified professional bouts

Three victories in Tokyo

On 29 September 2024, Yodkhunpon won three bouts at K-1 World MAX in Tokyo. He stopped Caan Pinar in the opening round of their quarter-final and Ionut Popa in the first round of the semi-final. The final against Shu Inagaki went to the judges, who awarded him a majority decision. K-1’s official result records two cards for Yodkhunpon and one even card. The contrasting finishes explain the achievement more clearly than calling the whole tournament a sequence of knockouts.

Winning an elimination tournament requires returning to compete after the earlier contests, but the verified outcomes do not tell us precisely how much fatigue or damage he carried between rounds. The defensible analysis is that he demonstrated more than one route to victory on the same programme: decisive early finishes and a successful full-distance final. That versatility is relevant to Cambodian readers familiar with marathon formats, while the K-1 rules remain distinct from a Cambodian elbow-permitting contest.

Returning to Muay Thai in 2026

At ONE Friday Fights 160 on 26 June 2026, he defeated Semih Sah Cindir by second-round knockout at Lumpinee. ONE’s recap described him absorbing an energetic opening before finding the decisive left-handed counter. The report identified Team Mehdi Zatout as his affiliation for that appearance. This newer reference is kept separate from the Weerasakreck Fairtex name used in K-1 material, since gym affiliations can change and promotional names may persist across career stages.

• His March 2022 Cambodian appearance is labelled Kun Khmer.
• The September 2024 title-winning run is labelled K-1 Rules.
• His June 2026 ONE debut is labelled Muay Thai and is not counted as a K-1 defence.

The result is a career profile built around documented transitions, rather than an undated combined record. Published promotional aggregates disagree, so no exact lifetime total is asserted here. For related opponents and competition context, consult the fighter directory and event archive. Yodkhunpon’s trajectory demonstrates why the history of a Kun Khmer opponent can remain relevant long after one Phnom Penh meeting, especially when later achievements are carefully identified rather than retrospectively attached to the wrong discipline.
