Robert Guerrero: 'Floyd Mayweather will run'

WBC welterweight challenger Robert Guerrero has claimed that Floyd Mayweather will run away from him in their upcoming title fight.

The 30-year-old has also said that Mayweather will "bring a big ring" to use at the fight.

The two fighters meet in Las Vegas on May 4, and Guerrero insisted that he has trained accordingly.

"I'm going to spar in a big ring," said Guerrero. "Because I know Floyd will bring a big ring.

"He will run like a chicken with no head, so I got to spar in a big ring."

Guerrero has only lost once in his 33 fights, with one draw, while Mayweather brings a perfect 43-0 record to the bout.
