LAS VEGAS- Floyd Mayweather Jnr will defend his WBC world welterweight title against Robert Guerrero on May 4 in Las Vegas.
The undefeated American, who spent two months in prison for assaulting his ex-girlfriend last year, has been out of action since outpointing Miguel Cotto last May.
Mayweather, 35, has also agreed a six-fight, 30-month deal with Showtime who will replace HBO as his pay-per-view broadcaster.
Having fought just six times in the last five years however, it would be a surprise if the pound-for-pound No 1 fulfils the terms of his contract. If he does, it will represent the richest deal ever signed by an athlete, according to reports.
'Floyd has signed a record-breaking deal with Showtime PPV/CBS and Floyd is ecstatic,' Mayweather's adviser Leonard Ellerbe told ESPN.com.
'This historic deal reflects a global superstar who is head and shoulders above his peers. HBO, they made a great offer but the Showtime PPV/CBS offer was substantially greater in every facet, from top to bottom."
