A few notes from around the boxing world:

• Puerto Rican lightweight Felix Verdejo (16-0, 12 KOs), the 21-year-old 2014 ESPN.com prospect of the year, is penciled in to make his HBO debut on June 13 -- the eve of the Puerto Rican Day parade in New York -- at the Madison Square Garden Theater, according to promoter Top Rank. The fight, which will likely be against 22-year-old San Antonio prospect Ivan Najera (16-0, 8 KOs), would open a card whose main event is not set. Verdejo, however, first has to come through a fight on April 25 (UniMas) in Guaynabo, Puerto Rico, where he will face Marco Antonio Lopez (24-5, 15 KOs). With middleweight champion Miguel Cotto having left Top Rank, the company is positioning Verdejo, whom many view as the island's next big boxing star, to take over the Puerto Rican parade weekend that Top Rank developed into a major fight weekend for Cotto.

• Junior welterweight up-and-comer Amir Imam (16-0, 14 KOs), 24, of Albany, New York, will take on Walter Castillo (25-2, 18 KOs), 26, of Nicaragua, on Showtime on April 18 at the StubHub Center in Carson, California, the network announced. Imam-Castillo will serve as the co-feature for the light heavyweight main event between former middleweight titleholder Julio Cesar Chavez Jr. (48-1-1, 32 KOs) and Andrzej Fonfara (26-3, 15 KOs). Castillo has fought all but one of his fights in Central America, having fought his last bout in Mississippi in October.

• Matchroom Boxing promoter Eddie Hearn and Barry McGuigan of Cyclone Promotions have been discussing a summer showdown between junior featherweight titleholders Scott Quigg (30-0-2, 22 KOs), whom Hearn represents, and Carl Frampton (20-0, 14 KOs), who is promoted by McGuigan.

"Two world champions from Britain in the same division -- they simply have to fight," Hearn said. "I have submitted my proposal to them and am waiting to hear what they have from their side. I feel we need to make progress now. The hope is for a summer fight, possibly on June 20. But all dates, venues and purse splits can't be decided until we know where we are going with the broadcaster. I think we need to reach some kind of agreement soon, probably the next two or three weeks, if we are to get this fight on in the summer. It really is the fight people want to see."
