Palmdale, California, lightweight prospect Joel Diaz Jr. (no relation to trainer Joel Diaz) will take on Luis Arceo in a scheduled 10-round bout on Aug. 29. The bout will be one of the televised fights on the undercard of Shane Mosley's rematch against Ricardo Mayorga, which will headline the pay-per-view card.

"Shane Mosley is a living legend. I looked up to him growing up, and I've been honored to know him, so being able to fight on the same card with him is a dream come true for me," said Diaz, 23.

Mosley (47-9-1, 39 KOs), the 43-year-old former three-division champion who knocked out Mayorga with one second left in the 12th round in 2008, is coming out of a nearly two-year retirement to face former two-division titleholder Mayorga (31-8-1, 25 KOs), 41, who has fought twice since 2011, at 158 pounds. The bout will take place at The Forum in Inglewood, California.

Mosley is doing double duty for the card. Besides fighting in the main event, his newly founded GoBox Promotions is the promoter of the show, which faces stiff competition from the ESPN-televised featherweight showdown between Abner Mares and Leo Santa Cruz. That fight will be taking place a few miles away at Staples Center in downtown Los Angeles and is on basic cable as opposed to a $50 pay-per-view between fighters who are very well known but not close to their primes.

Diaz (19-0, 15 KOs) is coming off a fourth-round knockout of journeyman Alejandro Rodriguez on July 25 on the Sergey Kovalev-Nadjib Mohammedi undercard. Mexico's Arceo (28-13-4, 18 KOs), 36, has lost two fights in a row by knockout (to former world title challengers Mercito Gesta and Jose Zepeda) and has not fought since July 2014.

"Diaz is a tremendous talent and a future world champion," Mosley said. "We are excited to have him stacking the Mosley-Mayorga PPV card."
