Floyd Mayweather Jr. (46-0, 26KOs) is viewed by many as being unbeatable in Las Vegas - if a fight goes to the scorecards. But recently, Mayweather has actually complained about the scorecards in his last two fights and the officiating in the ring.

Last September's win over Saul "Canelo" Alvarez was basically a one-sided fight, but one judge somehow scored the fight a draw 114-114. The judge in question, CJ Ross, is not longer working as an official. This past May, there seemed be no doubt about Mayweather winning a decision over Marcos Maidana, but yet again there was a judge who scored it a draw - 114-114.

A rematch with Maidana takes place next Saturday night at the MGM Grand in Las Vegas. Mayweather says there are no concerns with the judges.

"Well I think we're in the mecca of boxing, and we have the best commission in the world. So we probably need some new, young judges, whereas I think some of the judges now are a lot older and I think we need some new, young judges," Mayweather said.

Mayweather was also unhappy with the way referee Tony Weeks worked the May fight with Maidana. He claims Weeks allowed Maidana to get away with alleged dirty tactics throughout the fight. Veteran ref Kenny Bayless will work the rematch.

"I think Tony Weeks is an extraordinary referee. I think Kenny Bayless is an extraordinary referee. Tony Weeks is only human. He's capable of having a bad night. So it doesn't matter who the ref was going to be, we just want to go out there and entertain and give people something, give people an exciting fight. I'm pretty sure Kenny Bayless is going to be watching both sides extremely close," Mayweather said.
