Angel Matos had just been disqualified for exceeding the allotted injury time in the bronze medal taekwando match. The Cuban disagreed with the referee's judgment so he decided to show his displeasure by doing the only sensible thing: kicking the official in the head.
"Matos was winning 3-2, with 1:02 in the second round, when he fell to the mat after being hit by his opponent, Kazakhstan's Arman Chilmanov. He was sitting there, awaiting medical attention, when he was disqualified for taking too much injury time. 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."
Kicking? Spitting? Perhaps Matos should look into competitve tantrum throwing in 2012. Although he'd have some stiff competition.
