Floyd Mayweather Jr. and Manny Pacquiao are expected to have the first of only two news conferences in early March.  Pacquiao, meanwhile, left the Philippines because of the crazy fanfare and is expected to begin training in the United States next week.

The fight boxing fans have been waiting for is happening May 2, and they'll get their first taste of the Mayweather-Pacquiao blockbuster sometime in March, according to Pacquiao's side.

"According to (trainer Freddie) Roach and Pacquiao promoter Top Rank, the kickoff news conference for Mayweather-Pacquiao is expected to take place shortly after Roach returns from China -- likely March 10 or 11 in Los Angeles, where Mayweather and Pacquiao will meet head to head for the only time during the promotion," ESPN's Dan Rafael wrote Thursday.  "As big as the fight is -- expected to easily shatter every boxing revenue record -- there will not be a multicity promotional tour.

"Instead, there will be one kickoff news conference and then one a few days before the fight in Las Vegas."

In the meantime, Pacquiao, who was slated to start training on March 8, will begin his fight preparations early next week.

"Manny called me and said it's been so crazy in the Philippines that he is going to come over here early and probably start at Wild Card on March 2," Roach told ESPN on Thursday. "Having him early is really nice for me. We'll have Justin Fortune doing strength work with him, and then we'll begin the boxing part and start sparring."

The mega-fight is expected to break all pay-per-view records.
