Erik Morales has announced his next fight, and it will be part of the undercard of the September 17 HBO pay-per-view card, main evented by Floyd Mayweather Jr and Victor Ortiz.

Morales (51-7, 35 KO) will face UK lightweight Anthony Crolla (21-2, 9 KO), likely at 140 pounds. Morales is coming off of an incredibly brave performance in an April loss to Marcos Maidana, while Crolla, 24, won the vacant British lightweight in February.

It's an odd fight, but the 34-year-old Morales would in theory help draw in the faithful and big-spending Mexican audience for the pay-per-view. Saul Alvarez is also likely to be part of the telecast, though his fight won't take place at the MGM Grand in Las Vegas, where Mayweather and Ortiz will fight. Last reports were favoring Alvarez headlining in Los Angeles at the Staples Center, and the pay-per-view being a split site affair. Alvarez appears headed for a fight with either Alfonso Gomez or Ricardo Mayorga, with Gomez leading the race at this time.

It looks like Golden Boy is just hoping to set a 2011 PPV high mark with the return of Mayweather, plus a stab at bringing in the Mexican audience. It may well work, but whether or not the undercard is actually "good" will be another story.
