Floyd "Money" Mayweather says a one-year break including jail time won't stop him from retaining his WBC welterweight title defense against Robert "The Ghost" Guerrero. Mayweather, 43-0 with 26 knockouts, will make the mandatory title defense against Guerrero, 31-1 with 18 knockouts, on May 4 at the MGM Grand in Las Vegas, a year after beating Miguel Cotto by unanimous decision.

It will be Mayweather's first fight since serving two months in jail for domestic battery, a fact that gives challenger Guerrero a confidence boost.
