Notes: Mosley-Mayorga II in a tough spot

A few notes from around the boxing world:

•The junior middleweight rematch between former titleholders Shane Mosley and Ricardo Mayorga, scheduled for Aug. 29, will take place at The Forum in Inglewood, California. The $49.95 pay-per-view will be handled by Integrated Sports, but most definitely will be a hard sell at the gate and on PPV. Besides the fact that Mosley (47-9-1, 39 KOs), who is ending a nearly two-year retirement, and Mayorga (31-8-1, 25 KOs), who has fought two extremely low-level opponents in his only bouts since 2011, are well past their best days, they will be competing head-to-head with the long-awaited Leo Santa Cruz-Abner Mares featherweight showdown, which will take place just a few miles away at the Staples Center in Los Angeles in a fight that will air on ESPN. If you’re a fight fan are you going to pay 50 bones for a pay-per-view main event between two guys in their 40s or watch a big-time fight much fresher championship-level fighters in their 20s on basic cable? Mosley knocked out Mayorga with one second left in their 2008 junior middleweight bout on HBO in a fight that drew a crowd of only 5,798 in Carson, California.

•The IBF has three purse bid scheduled. Two are on July 28: Eamonn O’Kane (14-1-1, 5 KOs) versus Tureano Johnson (18-1, 13 KOs) in a final middleweight title eliminator for the right to become David Lemieux’s mandatory challenger and a final junior flyweight eliminator between Jonathan Taconing (21-2-1, 18 KOs) and Saul Juarez (21-4, 12 KOs) for the right to become the mandatory challenger to Javier Mendoza. On July 30, the purse bid is scheduled for the bantamweight mandatory defense between titleholder Randy Caballero (22-0, 13 KOs), who is coming off foot surgery, and interim titlist Lee Haskins (32-3, 14 KOs).

•Lightweight William Silva (21-0, 12 KOs), 28, of Brazil, has signed a promotional deal with Top Rank, the company announced on Wednesday. His first of the deal will take place Saturday night (UniMas) at the Florentine Gardens in Hollywood, California. "We expect big things from Silva in the lightweight division," Top Rank matchmaker Brad “Abdul” Goodman said. “With Silva and (middleweight prospect and 2012 Olympic silver medalist) Esquiva Falcao we expect big things in boxing in Brazil." Silva takes on Adam Mate (15-4, 9 KOs) in an eight-rounder on Saturday’s card.
