DANIEL CORMIER was furious after he claimed that Tyson Fury was not allowed enough time to recover from a Deontay wilder knockdown.
Fury was unable to breathe on the canvas after Fury fought Russell Mora.
Wilder had himself recovered from his knockdown in round three of their trio bout at Las Vegas' T-Mobile Arena.
The Bronze Bomber responded by sending Fury twice to the deck in the fourth, only for The Gypsy King not to climb back up to his feet before The 10-count.
Cormier suggested foul play while he viewed fight fans from around the globe.
He tweeted, "The count was insane slow. (The referee is not supposed to stop counting in order to tell Deontay that he should go to his corner.
Wilder's opponent was knocked to the ground by two powerful shots, but Fury stood upright at eight.
The rules of boxing state that a referee should stop the count if the fighter moves from his neutral side.
Wilder scored his first knockdown. He was instructed to go to a neutral spot, but instead he headed to his own corner - which could have delayed the count.
Cormier wasn't the only one to have concerns with the officiating. Wilder fans also jumped to his defense online.
One online video appears to show Fury falling to the ground and getting up ten seconds later. The ref did not count up to seven during that time.
After overcoming his early setbacks, the Brit was able to defeat his American opponent with a devastating right-hand in the 11th round.
