Because of the recent fallout with the Humberto Soto-Urbano Antillon rematch, the likely replacement to land on the undercard of the Manny Pacquiao-Shane Mosley pay-per-view is a junior welterweight bout between feared puncher Mike Alvarado (29-0, 21 KOs), and capable contender Ray Narh (25-1, 21 KOs). The Soto-Antillon rematch fell apart after Soto refused to sign the bout agreement and declared himself a free agent. Pacquiao-Mosley takes place on May 7 at the MGM Grand in Las Vegas. Showtime pay-per-view will televise.
