He was on one minute injury time out and past 60 secs, he was not on his feet yet. Technically he lost la.
So, this Cuban exponent was not satisfied. He threw a tantrum by injuring the referee.
All this happen during the bronze model match between Cuba's Angel Valodia Matos at the end of a bronze medal match against Kazakhstan's Arman Chilmanov in the the men's taekwondo +80 kilogram class. And if he did want to protest, he should have done it according to the rules.
*I guess he is no "Angel" after all*
Matos kicked Swedish judge Chakir Chelbat in the head as coaches from both teams ran on to the mat to dispute the result. The Cuban was leading 3-2 in the second period of the contest when Matos stopped to receive treatment for a foot injury. Competitors are allowed a one minute period to treat injuries, and when this time elapsed the referee awarded the contest to Chilmanov.
After a heated exchange on the mat, Matos pushed the match referee and then caught the Swedish judge in the head with a high kick. Matos then spat on the floor was promptly dragged from the scene by his back-room staff.
Matos and his coach were almost immediately slapped with a lifetime ban from all World Taekwondo Federation championships for the outburst, which the WTF called "a strong violation of the spirit of taekwondo and the Olympics." -source
