I don't think this is going to happen, I read somewhere at an interview with Floyd Mayweather that he is not interested with facing Senator Manny anytime soon or maybe not anymore as he (Floyd) is earning money without slugging it out with anybody in the ring. Floyd has a lot of endorsement lately and thats what keeps him busy nowadays.
But the money he got from endorsements is just peanut though as compare to fighting Manny which is going to be the biggest fight ever again. He goes out prior to the announcing of the winner in the Pacquiao-Thurman, because he knows for sure that he will be called out by Manny, hehehehe. He will be tempted to come back and fight Manny one last time -- if the price is right.
