WBC welterweight champion Floyd Mayweather is scheduled to begin serving his 90 day sentence in a county jail in Las Vegas today after pleading guilty to a misdemeanor battery charge last month. With good behavior, Floyd could be back on the street in 60 days. Floyd’s legal situation has scuttled a possible May showdown with Manny Pacquiao. Pacman is now expected to choose his next opponent from a short list consisting of Timothy Bradley, Miguel Cotto, Juan Manuel Marquez and Lamont Peterson. A decision could be made as soon as this weekend for a May or June date.
