Nong Oh Hama Muay Thai was knocked out by Assadullah Imankazaliev, missing out on the ONE Flyweight Muay Thai World Championship belt.
On 20 Mar 2026 GMT+7, the ONE Lumpinee 147 event took place at Lumpinee Boxing Stadium (Ramintra), featuring 14 top-tier fighters competing for global titles, broadcast live to more than 195 countries worldwide.
The main event featured 39-year-old Nong Oh Hama Muay Thai aiming to make history by moving down to the flyweight division (125-135 lbs) to fight for the vacant world championship belt. He faced 22-year-old undefeated Russian boxer Assadullah Imankazaliev, who had a 7-fight winning streak in ONE. However, at weigh-in, Assadullah missed weight at 139.8 lbs, so according to the rules, if he won, the title would remain vacant, but if Nong Oh won, he would immediately claim the belt.
The first round was cautious, with both fighters testing each other’s kicks. Nong Oh threw right kicks while Assadullah countered. Toward the end, Nong Oh landed a solid right kick.
In the second round, both fighters came forward more aggressively. Nong Oh increased his left kicks, but Assadullah closed in and landed a strong left punch, knocking Nong Oh down.
Assadullah Imankazaliev won by knockout over Nong Oh Hama Muay Thai in the second round but did not claim the world championship belt due to missing weight. Nong Oh narrowly missed out on winning the belt.
