An outraged French boxer screamed, kicked his mouthguard and shook a TV camera when he was disqualified at the Olympics on Sunday.
After the match, he remained on the canvas for an hour-long sit-in to protest the decision.
The incident occurred during Sunday's super heavyweight quarterfinal between France's Mourad Aliev and Great Britain's Frazer Clarke. Referee Andy Mustacchio disqualified Aliev with four seconds remaining in the second round after he determined that Aliev intentionally head-butted Clarke.
