A French super-heavyweight boxer lashed out at an injustice and sat in protest on the side of the ring after he was disqualified for headbutting in the Tokyo Olympics quarter-finals Sunday. 

In what was the first major controversy in the boxing in the Japanese capital, Mourad Aliev was disqualified in the second round against Britain’s Frazer Clarke. Aliev, 26, sat beside the ring ropes afterwards, seething, and claimed that officials had admitted they had made a mistake.
