FLOYD MAYWEATHER Jr. will fight Robert Guerrero on May 4, and he's changing television networks to do it.
The biggest star in boxing dropped a surprise Tuesday while announcing his long-rumored next bout: After several years on HBO, Mayweather is moving to Showtime with a lucrative multifight deal.
Mayweather's move is a coup for Showtime, the CBS-owned network that has always trailed behind HBO in boxing prominence. Mayweather (43-0, 26 KOs) is the sport's biggest moneymaker, and his new revenue-sharing deal with Showtime could include up to six pay-per-view fights over 30 months.
