Orozco, Dirrell added to Cosmo card

One of my favorite prospects, exciting junior welterweight Antonio Orozco, is getting back to work after being sidelined briefly because of an injury.

San Diego’s Orozco (16-0, 12 KOs), 25, will face Jose Reynoso (16-4-1, 3 KOs), 28, of Riverside, Calif., in a scheduled eight-rounder at The Cosmopolitan in Las Vegas on May 3, Golden Boy Promotions announced Friday.

The fight is part of a Fox Sports Net/Fox Deportes card (11 p.m. ET) taking place on the eve of the Floyd Mayweather Jr.-Robert Guerrero welterweight title fight at the MGM Grand.

That means Las Vegas will be filled with fight fans, many celebrating Cinco De Mayo, and media, some of whom will be at the show and getting a good look at Orozco and others on the card.

The co-feature was also announced. That eight-rounder will feature super middleweight Anthony Dirrell, the younger brother of former super middleweight title challenger and 2004 Olympic bronze medalist Andre Dirrell. Anthony Dirrell does not have an opponent yet.

Anthony Dirrell (24-0, 21 KOs), 28, has not fought since December 2011 because he was injured in a motorcycle accident. He had another layoff of nearly two years as he successfully battled non-Hodgkin's lymphoma in 2007.

In previously the previously announced main event, Francisco Vargas (15-0-1, 12 KOs) of Mexico faces Jose Aguiniga (33-0, 15 KOs) in a 10-round junior lightweight contest.

The card will also feature a pair of 2012 U.S. Olympians, junior middleweight Errol Spence Jr. (4-0, 3 KOs) of Dallas and junior featherweight Joseph Diaz Jr. (3-0, 1 KO) of South El Monte, Calif.
