Las Vegas – Floyd Mayweather Jr called out Manny Pacquiao on his Twitter on Monday writing in his first tweet “”Manny Pacquiao I’m calling you out let’s fight May 5th and give the world what they want to see,” then he fired off “My Jail Sentence was pushed back because the date was locked in. Step up Punk.” Mayweather was due to report to jail last Friday to begin his 90 day sentence but was awarded a stay of execution by the judge to help fulfill his contract obligation for a fight at the MGM Grand on May 5th.
