Top Rank's CEO Bob Arum has confirmed that junior middleweight contender Vanes Martirosyan (32-0-1, 20KOs) will return on April 6th on the undercard of the big event being planned on April 6th in Macau. The main event will feature the pro debut of Olympic gold medal winner Zou Shiming, who recently signed a contract with Top Rank. BoxingScene reported last week that super bantamweight contender Wilfredo Vazquez Jr. will see action on the card, and Brian Viloria will defend his WBA/WBO flyweight belts against Juan Estrada.

Vanes will likely face Javier Maciel of Argentina (24-2, 17KOs).

There have been some discussions with K2 Promotions, confirms Top Rank VP Carl Moretti, about possibly matching Vanes against WBO champion Zaurbek Baysangurov (28-1, 20KOs), who plans to make a March title defense in Eastern Europe.
