Moments later, Hamedi was disqualified for a hansoku, a serious violation of the rules. The NBC television broadcast said he had unleashed an unchecked attack, following through on his strike as a mixed martial artist would, which is considered too dangerous by Olympic karate standards. Ganjzadeh, who was informed of the decision when he regained consciousness, was awarded the gold medal, and Hamedi was given silver.
