Floyd Mayweather Jr., who has steadfastly refused to answer questions about the most recent round of failed negotiations for a fight with Manny Pacquiao, has unleashed a profanity-filled racist and homophobic Internet rant against the Filipino star.
In an approximately 10-minute Ustream video, apparently made Thursday and also posted on YouTube, Mayweather repeated his assertion that Pacquiao uses performance-enhancing drugs, an accusation that resulted in a defamation lawsuit from Pacquiao earlier this year.
Mayweather, apparently in his home with a handful of members of his entourage in the background, ripped into Pacquiao repeatedly during the video.
"I'm on vacation for about a year, about a year," Mayweather said. "As soon as we come off vacation, we're going to cook that little yellow chump. We ain't worried about that. So they ain't gotta worry about me fighting the midget. Once I kick the midget ass, I don't want you all to jump on my d---. So you all better get on the bandwagon now. ... Once I stomp the midget, I'll make that mother f----- make me a sushi roll and cook me some rice."
Mayweather's publicist, in Mexico for another fighter's promotion, has seen the video but has been unable to reach Mayweather or adviser Leonard Ellerbe. Kelly Swanson said she would not comment further.
Attempts by ESPN.com to reach Ellerbe were also unsuccessful.
Pacquiao dismissed the video, choosing to instead focus on his upcoming fight with Antonio Margarito on Nov. 13 at Cowboys Stadium near Dallas.
"I just heard about that, but I didn't see the video," Pacquiao said Friday, at the final stop of a three-city tour to promote his fight. "But it's an uneducated message."
When asked about the possibility of a Mayweather bout Friday, Pacquiao responded: "I'm not looking for that fight. I'm satisfied with what I've done in boxing already."
In the video, Mayweather at times spoke directly to the camera and at other times kept the recording running while he made calls to fans who had posted messages to his UStream and Twitter pages.
The tirade came as Pacquiao promotes his fight against Margarito -- a bout taking place only because Mayweather refused to fight him.
But Mayweather sure made it sound as though a fight with Pacquiao, one many believe will shatter revenue records in boxing history, will eventually happen. They have already had two rounds of negotiations fail -- in January and again during the spring.
"At this particular time I don't know if I'm gonna fight again," Mayweather said. "As of right now, I truly believe I am gonna fight again, but as of right now I don't have the urge to get up. But when I do got the urge to get up, believe me my UStream and my Twitter fans will be the first to know, and when we do come back, we will kick 'Poochiao' ass. So I'll let the fans know. Don't worry, we'll kick 'Poochiao' ass. He's gonna take the urine and blood test."
All terms had been agreed to in January for Mayweather and Pacquiao to meet in March, except for the drug-testing protocol. Mayweather had demanded that he and Pacquiao submit to random blood and urine tests throughout the buildup to the fight. Pacquiao agreed to random urine tests, but they could not come to an agreement on the blood-testing protocol and the fight plans imploded.
Pacquiao went on to easily defeat Joshua Clottey on March 13. Mayweather went on to easily outpoint Shane Mosley on May 1.
Then a second round of negotiations failed and Pacquiao signed to fight Margarito.
During this week's media tour to promote the bout, Pacquiao said he gave in to Mayweather's testing demands during the second round of negotiations.
"We agree with, you know, his demands," Pacquiao said. "I wanted to know if that's his real reason [for not signing to fight]."
Mayweather's camp has denied the second round of negotiations ever took place, even though Pacquiao's promoter, Bob Arum, insisted that they did, with HBO Sports president Ross Greenburg serving as the intermediary. Arum's version was backed up by Greenburg, despite the Mayweather camp's denials.
During the video, Mayweather also went on a rant about Pacquiao's record, even though Pacquiao has not lost a fight since 2005, and made incorrect comments about the money each had received for recent fights and endorsements.
" 'Poochiao' got three losses and two draws and been knocked out twice," Mayweather said. "So, like I said before, once I beat him it's going to be a cakewalk and it's on to the next. ... We know Pacquiao made $6 million in his last fight and Floyd Mayweather made $65 million in his last fight. Three losses, two draws. Ohhh, hell no, this is America baby. We built on winning. Step your game up, f----t. ... That mother f----- Pacquiao, he can't speak no English. He never seen a contract he didn't like. Mother f----- signed with two companies [Top Rank and Golden Boy]. Look it up. And then this mother f------ with Nike only got 70 Gs. How stupid can a mother f----- be? Reebok gave me a million dollars for three weeks. I wore Reebok s--- for a week for a million dollars. ... This mother f------'s name is Emmanuel. He got a fake name, taking power pellets."
Mayweather also broke out into a bizarre song in which he called Pacquiao a "whore" and added: "When we do come back, we'll kick 'Poochiao's' ass. I'm gonna fight the Pacman when he gets off the power pellets."
