Leonard Ellerbe, one of Floyd Mayweather Jr.'s closest advisers, denied Monday that negotiations for a super fight between Mayweather and Manny Pacquiao had ever taken place.

That is contrary to what Top Rank's Bob Arum, Pacquiao's promoter, has been saying for the past three weeks, and he's sticking by his story.

Arum said June 30 that he had concluded talks and was waiting for a decision from the Mayweather camp on whether he wanted to fight this year. Then, Arum gave Mayweather until 3 a.m. ET Saturday to accept the terms of an agreement, or he would move on and look to make a deal for Pacquiao to either fight Antonio Margarito or have a rematch with Miguel Cotto on Nov. 13.

There was even a clock on Top Rank's website counting down the days, hours, minutes and seconds until the deadline, a deadline Arum said was the window in which he would exclusively negotiate the Mayweather fight.

Arum set a teleconference with boxing reporters at the deadline's expiration. On the teleconference, Arum said he had worked out the agreement with Al Haymon, Mayweather's top adviser, using Ross Greenburg, the president of HBO Sports, as a go-between without ever speaking directly to Haymon.

Now, Ellerbe denies any of that ever happened.

"Here are the facts," Ellerbe said in Monday's statement. "Al Haymon, [Golden Boy Promotions CEO] Richard Schaefer and myself speak to each other on a regular basis, and the truth is no negotiations have ever taken place, nor was there ever a deal agreed upon by Team Mayweather or Floyd Mayweather to fight Manny Pacquiao on Nov. 13. Either Ross Greenburg or Bob Arum is not telling the truth, but history tells us who is lying."
