UFC champion Conor McGregor is still very upset with the officiating for his August TKO loss at the hands of Floyd Mayweather Jr.

McGregor was making his professional debut as a boxer and took on five division champion Mayweather, who was coming out of retirement.

The fight, which took place at the T-Mobile Arena in Las Vegas, saw an exhausted McGregor get stopped in the tenth round of the fight.

McGregor still believes Byrd jumped in way too early to wave off the fight. He felt Byrd should have at least allowed him to go down. McGregor denies being hurt at the time of the stoppage and blames fatigue for being unsteady on his feet.

“I thought it was an early stoppage. How the f*** can you stop a fight if there were no knockdowns or nothing previous? The round before that I almost had him dropped. I hurt him to the body in the round before. How the f*** can you stop it like that at the first sign of a wobble? You’ve got to let these fights go on,” McGregor told interviewer Caroline Pearce.

McGregor also brought up Byrd's wife, Adalaide Byrd, who is still getting slammed for her scorecard in last month's middleweight showdown between Gennady Golovkin and Canelo Alvarez. While almost everyone saw a close fight, Adalaide scored it 118-110 in favor of Canelo. Her unexplainable scorecard resulted in her immediate removal from all major bouts for the foreseeable future.

“The referee was a weird one now the more I look back on it,” McGregor said. “Especially after Adalaide Bird had that thing with the Canelo and GGG fight, that was her. Adalaide and Robert Byrd are husband and wife, that’s a bit weird, that’s when I started looking back on the fight.

“Why did he not give (Mayweather) instruction? Why was he staring at me? He had a vendetta against me straight off the bat. Early exchanges in the tie up, instead of just separating he would reach around and pull me away.”
