The fight is indeed happening as the pound for pound champ Manny Pacquiao agreed on the March 13 date in what is seen as the fight of the century.
Pacquiao met with Bob Arum recently in Manila and reportedly agreed in principle the terms laid down by Mayweather's camp.
Pacquiao did asked for some requirements which Arum believed won't hinder the negotiations, ike the type of gloves to be used.
Michael Koncz, Pacquiao's Canadian adviser, said that even though no contract has been signed yet the fight is a "done deal."
The fight would be at 147 pounds for Pacquiao's WBO welterweight title, which he won in November with an impressive 12th round stoppage of Miguel Cotto in Las Vegas.
The bout could be the richest ever assuming projections are accurate. Pacquiao's fight against Cotto sld 1.25 million pay-per-views, while Mayweather's comeback victory over Juan Manuel Marquez in SEptember did 1.05 million.
