Trainer Floyd Mayweather Sr. is fuming after watching a recent video on BoxingScene.com, where Ruben Guerrero was training for a street fight showdown with Floyd Sr. Over the last few weeks, the two trainers have exchanged numerous threats through the press. Both trainers have promised vicious knockouts in a potential street fight at the MGM Grand's parking lot on May 4th. Later that night, their two sons will battle it out on Showtime Pay-Per-View. Floyd Sr. will work the corner of Floyd Mayweather Jr., while Ruben is the trainer of mandatory challenger Robert "The Ghost" Guerrero.

Floyd Sr. told Percy Crawford of Fighthype.com:

"I'm not even gonna get in shape for this one because I'm fighting a bum. Get in shape for what? I saw him doing one-arm pushups and all of that sh*t. He gonna need more than one-arm pushups because I'm gonna knock his ass out. You already know what's about to happen and I can't wait."

"He's comedy to me. I don't even want to fight him, man, but watching that video...see, before, I wasn't even mad. That video got me just mad enough to rip his f***ing head off now. He on video showing his scars and all that sh*t. That sh*t don't mean nothing, man. He gonna be able to show a fresh set of scars after I get a hold of his ass; scars upside his f***ing head. I'm gonna beat the socks off of his ass. He doing one-arm pushups and lifting weights, but what his ass need to be buying is a pair of roller skates.
