NEW YORK (WFAN) -- Unbeaten boxer Floyd Mayweather Jr. isn't a fan of Linsanity.

UFC president Dana White? He's not too keen on Mayweather.

White took Mayweather to task this week for posting a racially charged comment on Twitter about Knicks star Jeremy Lin.

"First of all, what he said, I think, is racist," White said during his "Presidential Address" segment Tuesday on Fuel TV. "He's made a couple of racist comments. And yes, Floyd, you're racist with the stuff that you've said."

Mayweather tweeted last Monday: "Jeremy Lin is a good player but all the hype is because he's Asian. Black players do what he does every night and don't get the same praise."

Lin's popularity has skyrocketed since emerging from the Knicks' bench nearly three weeks ago. As the NBA's first American-born player of Chinese or Taiwanese decent, the Harvard product's improbable saga has touched basketball fans across the globe.

The boxer was criticized heavily for his comment, but wouldn't back down in a series of posts. "Other countries get to support/cheer their athletes and everything is fine," Mayweather wrote. "As soon as I support Black American athletes, I get criticized."

White was emphatic in his rebuttal.

"Kobe Bryant doesn't any praise? Michael Jordan never got any praise?" he said. "The list goes on and on of guys who completely get praised for being great NBA basketball players. Not only can he compete and make it in the NBA, the guy's tearing it up and is breaking records, you knucklehead."

Rival boxer Manny Pacquiao has also been on the receiving end of Mayweather's mouth. White said it's time to quit it and get in the ring with the Filipino congressman.

"Don't worry about what all these other guys are doing and shooting your big mouth off on Twitter," said White. "What you should worry about is getting in there and making the fight that all the boxing fans want to see. Get in there and fight Manny Pacquiao!"

Mayweather will witness Lin-mania firsthand Thursday night. He has tickets for Knicks-Heat in Miami, according to The Associated Press.
