R. Rios on the comeback trail

A few notes from around the boxing world:

• Featherweight Ronny Rios, a rising contender on the verge of fighting for a world title, suffered an upset fifth-round knockout to Robinson Castellanos in October. Now Rios is on the comeback trail and slated for his fight since that stunner. Rios (23-1, 10 KOs), 25, of Santa Ana, California, will face Mexico’s Jesus Navarro (23-9-1, 16 KOs) on March 20 (Fox Sports 1/Fox Deportes) at the Fantasy Springs Resort Casino in Indio, California, Golden Boy announced on Friday. The fight is the co-feature on the card headlined by Mexican junior middleweight Alfonso Gomez (24-6-2, 12 KOs), a two-time world challenger and for star of “The Contender” reality series, taking on Japan’s Yoshihiro Kamegai (25-2-1, 22 KOs).

• Lightweight contender Sharif Bogere (26-1, 18 KOs) and Jose “Chelo” Gonzalez (23-1, 18 KOs) will square off on April 11 (PPV) in San Juan, Puerto Rico, on the undercard of junior lightweight titlist Orlando Salido (42-12-2, 29 KOs), of Mexico, defending against Puerto Rico’s Roman "Rocky" Martinez (28-2-2, 17 KOs), the former titleholder, PR Best Boxing Promotions announced Friday. Bogere, from Uganda but living in Las Vegas, suffered his only loss in a world title fight, losing a decision to Richar Abril in Las Vegas in March 2013. Gonzalez’s only loss was also in a world title fight in May 2013. He faced Ricky Burns in Burns’ home country of Scotland and was winning but quit because of a wrist injury after the ninth round.

• Junior featherweight prospect Joseph Diaz (14-0, 9 KOs), a 2012 U.S. Olympian, got a new opponent this week for his 10-round bout that will headlined the debut of Golden Boy’s revived “LA Fight Club” series on March 6 (Fox Sports 1/Fox Deportes, 10 p.m. ET) at the sold-out Belasco Theater in downtown Los Angeles.
