Irish Olympian boxer, Michael Conlan, accused the Olympic judges and Russia of a conspiracy theory.

Conlan faced Vladimir Nikitin of Russia in the quarterfinals of the 56 kilogram division. He seemed to win the match, but the judges overseeing the match gave the decision to Nikitin.

The judge decided events at the Olympics have a long history of conspiracy theories and boxing is an event rich with controversy.

Most infamously, American boxing legend, Roy Jones Jr., appeared in the 1988 Seoul Olympics, where he seemed to clearly defeat South Korean boxer, Park Si Hun in the title bout.

The judges awarded Park Si Hun the gold medal and, according to Jones Jr., the South Korean athlete later apologized to him personally for the unjust decision.

Even the 2016 Olympic games have seen their share of controversy in the boxing events.

American Gary Russell also seemed to have been cheated in a disputed decision.

“[Russell had] clearly been robbed,” remarked Floyd Mayweather Jr., who was in attendance to root for the American athletes.

After his defeat, Conlan went on an explosive laden rant and flipped off the judges.

“AIBA (International Boxing Association) are cheats,” remarked Conlan. “They’re (expletive) cheats. I’ll never box (under) AIBA again. They’re cheating bastards. They’re paying everybody. I don’t give a (expletive) that I’m cursing on TV. My dream has been shattered now, but you know what, I have a big career ahead of me. They’re known for being cheats. They’ll always be cheats. Amateur boxing stinks from the core right to the top.”
