Chilmanov was the other competitor in the controversial +80 kg bronze medal match against Ángel Matos of Cuba.
He was behind 3-2 in the second round when his opponent sustained an injury to his toe. Matos took a Kyeshi - one minute of injury recovery time - but Chilmanov was declared the winner of the bout when the Cuban's timeout expired. After a brief argument, Matos kicked referee Chakir Chelbat in the face, pushed a judge and spat on the floor of the arena before being escorted out by security, and was subsequently banned for life, along with his coach Leudin González. After the chaos, he commented "To me it was obvious he (Matos) couldn't continue, the toe on his left foot was broken. Rules are rules, I'm happy with my medal".
