Boxingtalk.com has been informed that the mega-fight between pound for pound kingpins Manny Pacquiao and Floy Mayweather Jr is dead in the water and will not take place on March 13 at the MGM Grand in Vegas as was originally planned. Pacquiao’s lawsuit appears to have put the final nail in the coffin and fans should expect a formal announcement to follow shortly! Richard Schaefer, Bob Arum and Leonard Ellerbe were all unavailable for immediate comment. Boxingtalk.com also believes that Pacquiao will keep the March 13 date for a potential fight with junior middleweight champion Yuri Foreman or junior welterweight contender Paulie Malignaggi.
