(AllHipHop News) Floyd Mayweather and Sugar Shane Mosley will hit the Nasdaq tomorrow (March 2), where the two rivals will unite to ring the opening bell to promote their May 1st boxing match in Las Vegas. The event is part of a tour the two boxers are on to promote their highly anticipated bout two months from today. Mayweather recently checked in with AllHipHop.com, where he discussed a number of topics, ranging from the failed match with Manny Pacquiao, his decision to take on Sugar Shane Mosley, and his former Hip-Hop rival with rapper Rick Ross. Mayweather trashed Manny Pacquiao during the interview for not taking a “$25 million dollar” random blood, urine and drug tests.“I felt that in today’s time, there’s too much cheating going on in all sports, I’m not just making a stand in boxing, I’m making a stand in all sports. It’s about being fair,” Mayweather told AllHipHop.com. “We got athletes that live in our own country that lie to American citizens about taking certain enhancing drugs. Manny is not even from this country, he doesn’t live in this country. Imagine what he would tell the American people.” Mosley (46-5, 39 KOs) , who has won seven out of his last eight fights, had no issues with taking the tests and has agreed to the Olympic-style random blood testing. During the interview with AllHipHop.com, Mayweather shot down Mosley’s comments that he was “stronger, faster and better” than Mayweather. “I wouldn’t have chose the fight with Shane if it wasn’t a good fight, a solid fight. But I’m an A-lister, and Shane Mosely is a C-lister,” Mayweather told AllHipHop.com. “But when you involve yourself with the Mayweather brand, it takes you to the next level in the sport of boxing.”Outside of the ring, Mayweather and rapper Rick Ross squashed their growing feud, although the boxing champion took issue with Sean “Diddy” Combs’ proclamation that rapper Rick Ross was the next “Biggie Smalls.” Ross, who is featured on Diddy and Dirty Money’s remix to “Angels,” has had a well documented feud with rapper 50 Cent, in addition to Floyd Mayweather. The pair buried the hatchet last month, after a New Year’s celebration almost turned violent when their respective entourages clashed at a party hosted by Diddy at new nightclub, Vanity, inside of the Hard Rock Hotel. “I hear lately that Puff Daddy has been saying Rick Ross is the next Biggie Smalls. That’s not true,” Mayweather told AllHipHop.com. “He’s a good artist but he’s not the next Biggie Smalls. There’s only one Biggie and there’s only one Pac. The thing is this, rap is story telling. It’s not true. If somebody had those many guns, done that much killing or sold that much work or hustled that much, of course they would be in prison.”Mayweather admitted that Rick Ross is a good Hip-Hop artist, but stated that he has no plans on supporting the rapper’s releases. “A lot of times people think I’ma downplay somebody because we may not get along or we may not see eye to eye,” Mayweather told AllHipHop.com. “He’s had songs that’s been cool. I’m not saying that I’m a fan or I’m gonna go buy his album. The only thing I can say is Floyd Mayweather is in his lane. I stay in my lane and I want everyone else to stay in their lane. Period.” Mayweather and Mosley will hit the road to promote their May 1st boxing match starting tomorrow (March 2nd) in New York.
