A Cuban taekwondo athlete has attacked the referee after losing his bronze-medal match. Angel Matos was declared the loser for taking too much injury time after hurting his leg during the men's over-80 kg match. Fighters get one minute, and Matos was disqualified when his time ran out. Matos angrily questioned the call, pushed a judge, then pushed and kicked referee Chakir Chelbat of Sweden. Matos then spat on the floor and was escorted out. It was not immediately clear whether Matos would be punished.
