MGM Grand, Las Vegas - At 2:30PM PT/5:30 EST, Floyd Mayweather Jr. and WBC welterweight champion Victor Ortiz will step on the scale to make weight for Saturday's big pay-per-view headliner at the MGM Grand in Las Vegas. A few weeks ago Mayweather was already two pounds away from the welterweight limit, while Ortiz was closer to middleweight. Mayweather claims Ortiz is having weight issue, and the champion wants to prove him wrong.
