RIO DE JANEIRO -- One day before Newark boxer Shakur Stevenson is set to fight in the Olympic semifinals and one day after charges of fixed fights were thrown like uppercuts at the boxing venue, several judges and referees have been suddenly suspended.

The AIBA, the federation that governs amateur boxing, refused to reveal the names of the referees and judges dismissed or reveal which fights were in question. In a statement, the organization said it had assessed all 239 bouts at the Rio Olympics through Tuesday and had "determined that less than a handful of the decisions were not at the level expected."

So maybe Michael Conlan, who lashed out in a profanity-laced tirade after judges awarded his quarterfinal fight to Russian rival Vladimir Nikitin, wasn't so far off target. Several observers, including Stevenson, thought Conlan had clearly won the wild fight.

Stevenson will face Nikitin next with a spot in the gold-medal bout on the line. When asked how he could prevented against such a decision going against him, he said he to take the decision out of the judges' hands.

"I guess I've got to make it clear," he said. "I felt Conlan made it clear, honestly. I watched it right before my fight. I thought he made it clear but the judges felt different. I plan on going in there focused on what I'm going to do and not worry about the judges or anything."

Stevenson, who is "the next Floyd Mayweather" according to the boxer himself, will fight Nikitin at 1:30 p.m. ET. The fight will be live streamed on NBCOlympics.com.
