The Court of Arbitration for Sport (CAS) on Tuesday rejected French boxer Mourad Aliev's appeal over his Tokyo Olympics disqualification for headbutting his opponent Frazer Clarke.

For as long as boxing has been in the modern Olympics, fighters and fans have complained about it.

France’s Mourad Aliev staged an hour-long, ringside "sit-in" following a second-round disqualification in his super heavyweight quarterfinals match against Great Britain’s Frazer Clarke at the 2020 Tokyo Olympics.
