WORLD CHAMPIONSHIP BOXING: SHANE MOSLEY VS. RICARDO MAYORGA AND ANDRE BERTO VS. STEVE FORBES

Expect a September heat wave when former lightweight, welterweight and junior middleweight champion "Sugar" Shane Mosley (44-5, 37 KOS) stands toe-to-toe with Ricardo "El Matador" Mayorga (28-6-1, 22 KOS), one of boxing's most animated fighters, in a 12-round junior middleweight bout. In his first fight in Southern California since 2000, Pomona, Cal., native Mosley returns to the ring in search of another title shot. A native of Managua, Nicaragua, Mayorga hasn't fought since handling Fernando Vargas last November. He's never ducked a challenge, having tangled with Vernon Forrest, Felix Trinidad and Oscar De La Hoya.

In the opening bout, newly crowned welterweight titleholder Andre Berto (22-0, 19 KOS) defends his belt against crafty veteran Steve Forbes (33-6, 9 KOS) in a 12-round, 147-pound tilt. Florida native Berto captured his first title by defeating never-before KO'd Miki Rodriguez in June, scoring his 19th knockout in just 22 fights. Las Vegas resident Forbes is a formidable contender who elevated his status significantly last May when he went the distance against Oscar De La Hoya.
