Mayweather says Maidana no pushover

Unbeaten champion acknowledges Argentine slugger has puncher's chance

All the signs indicate that five-division world champion Floyd Mayweather Jr. will comfortably extend his unbeaten record when he faces Argentina's Marcos Maidana on Saturday - though the American is not expecting a pushover.

Mayweather, who has a 45-0 record with 26 knockouts, is an overwhelming 11-1 favorite for the WBC/WBA welterweight title unification bout at the MGM Grand Garden Arena in Las Vegas.
