There will be no fight between welterweight champions Manny Pacquiao and Floyd Mayweather Jr..

Both Leonard Ellerbe, one of Mayweather’s advisors, and Richard Schaefer, Golden Boy Promotions CEO, said that Pacquiao’s promoter Bob Arum of Top Rank was not interested in negotiating a fight.

“We have been informed that Bob Arum is not interested in pursuing a fight between Mayweather and Pacquiao at this time.”

Mayweather returned to the ring in September after a 16-month layoff and knocked out Victor Ortiz. Pacquio beat rival Juan Manuel Marquez in a controversial majority decision on Saturday night.

Schaefer said that he received the news that Arum was not interested in a Pacquiao-Mayweather fight from retired federal judge Daniel Weinstein, who has worked closely with both sides to settle issues in recent years.
