Floyd Mayweather Jr. claims racism is still rife in boxing and other combat sports, as is illustrated by the support UFC featherweight champion Conor McGregor and former women's champion Ronda Rousey receive.
The former undisputed five-division world champion says he got crticised for trash-talking ahead of fights, but McGregor and Rousey have both received praise for being outspoken.
In an interview with FightHype, the 38-year-old added that undefeated super middleweight champion Andre Ward doesn't get the respect he deserves on the pound-for-pound rankings because "racism still exists in the sport of boxing."
"You gotta really look at things like this, when Bernard Hopkins was a middleweight trying to fight Oscar De La Hoya, Shane Mosley, and Felix Trinidad, they [the media] said he was calling out smaller guys. When the guy Triple G [undisputed middleweight champion Gennady Gennadyevich Golovkin] does it, they don't say s***," Mayweather said.
"I'm not racist; I'm just saying racism still exists. Do I think that they're trying to get Andre Ward beat? Absolutely! Andre Ward, if you're reading this article, if I was you, I wouldn't move up to 175 pounds to fight the guy, Kovalo [Sergey Kovalev], if that's his name, because I really don't know his name.
"I know he's a light heavyweight. Andre Ward is a 168-pounder and I think he should continue to dominate at 168. This is what I think should happen. You know, everybody keeps talking Triple G, so I just started taking notice probably last year.
"If this guy Triple G is so tough and so bad, you know, from what they say, then let him go up and fight Andre Ward. Once again, these guys in boxing [media], not me, are rating this guy, Triple G, super high.
"He's good with a stationary target in front of him. When he's fighting a guy that's straight up and down with no special effects, is he good? Absolutely! But do I think that Triple G can beat Andre Ward? Absolutely not! Easy pickings! It's going to be very, very, very easy for Andre Ward."
Mayweather then layed into McGregor, saying he had never even heard of him before a member of his entourage said the Irishman is one of the most outspoken fighters in the world.
"I don't really know the McGregor guy; never seen him fight. They say he talks a lot of trash and people praise him for it, but when I did it, they say I'm cocky and arrogant," Mayweather continued.
"So biased! Like I said before, all I'm saying is this, I ain't racist at all, but I'm telling you racism still exists."
Rousey, who has been involved in verbal jibes with Mayweather on more than one occasion in the past, was next on the agenda for the legendary pugilist.
"Ronda Rousey, you know, I think she fought somewhere like 11 or 12 fights, which is not a bad thing," Mayweather added.
"Laila Ali went undefeated and was dominating too. After Ronda Rousey fought I think 9, 10, 11 fights, it didn't even take that long, she got all types of endorsements, movies, and everything.
"Laila Ali did the same thing in better fashion. Ronda Rousey, she's a good looking woman when she put it on. Laila Ali is a drop-dead gorgeous woman; I mean a naturally beautiful woman and can kick ass, but you never heard (the media) saying when she had I think somewhere around 10, 11, 12 fights that she was the baddest woman to ever fight on the planet."
