The American, who comfortably beat Manny Pacquiao on points in their hugely-anticipated megafight in Las Vegas, confirmed that he would fight once more, in September, but that it may not be a world title bout.
Mayweather holds the WBA, WBC and WBO titles but he could give them all up as early as next week.
“My last fight may not be a championship fight,” he said. “I might give up all my belts. Why? Give other fighters a chance. I’m not greedy.”
In his post-fight press conference, Mayweather hit out at the assembled media, who he feels have not given him enough respect over the years.
???I try to keep myself away from negative publicity. People don???t really know me. I???m a person who loves his family. I only want the best for my family. I???m an American dream.
“I knew I had him from round one. I have so much experience I could calculate his moves.??I was born a winner and I am going to die a winner.
???I???ve worked hard to put my family in a great situation. But tomorrow, for all those who wrote bad stories about me, I???m going to wake up early and see your stories.
“Everyone’s been saying for years that I was scared and I would lose. Everyone said this guy could beat Floyd. That Floyd is a chicken. The non-believers, well Floyd turned them into believers.”
Mayweather said that only his desire to keep his word and fulfil his six-fight Showtime contract will see him fight again in September.
“My last fight is in September, and then it’s time for me to hang it up,” the 38-year-old said. “I’m almost 40 years old now. I’ve been in this sport for 19 years and have been a champion for 18 years. I’m truly blessed.”
Mayweather admitted that the financial rewards of meeting Pacquiao are incredible, even by his standards.
“For my team to hand me a $100 million check is remarkable,” said Mayweather, whose take from the long-awaited mega-fight with Pacquiao could eventually swell to as high as $200m once all the record-breaking revenue is counted.
The man who has named himself “Money” said the pay-out was all part of a “brilliant game plan” for his career.
“My goal was to make nine figures in one night,” he said.
