In another display of that Olympic spirit and sportsmanship we keep hearing about, a Cuban Taekwondo fighter kicked a referee square in the chops (pictured) after he was disqualified for taking too much injury time.
Now, I've got no problem with him protesting the outcome of his match if he thinks he was wronged, but this is just scary. The World Taekwondo Federation is talking about banning him for life and that's probably the correct move. If there's anything there has to be zero tolerance for in a fighting sport, I think this might be it.
