Petchmorrakot Petchyindee’s win over Giorgio Petrosyan at ONE: ‘Enter the Dragon’ last weekend has been overturned. The bout has been ruled a no-contest due to the referee’s failure to ‘adequately control the illegal clinching’.

ONE Championship CEO Chatri Sityodtong explained the decision in a Facebook post:

Petrosyan clearly won the opening round. But Petchmorrakot switched strategy after that and started to dominate the two time K-1 Max winner in the clinch.

The winner of the bout is scheduled to face Jo Nattawut in the semi final of the ONE Featherweight Kickboxing Grand Prix. The stakes for the tournament were raised dramatically last week when the promotion announced a $1 million USD prize for the winner.

In the other semi final Samy Sana faces Dzhabar Askerov. The tournament is set to conclude at ONE: ‘Century’ in October meaning that the rematch between Petchmorrakot and Petrosyan will need to take place very soon.
