A deal for a featherweight title unification bout between Shakur Stevenson, who won a vacant belt by one-sided decision over Joet Gonzalez on Oct. 26, and fellow undefeated titlist Josh Warrington, who has made three defenses, is on track, Top Rank chairman Bob Arum, Stevenson's promoter, told ESPN on Tuesday. He has been in talks with Warrington promoter Frank Warren. "We're making good progress with Frank about doing it," Arum said, adding that if the deal is finalized the fight, which would air on an ESPN platform in the United States, likely would take place in April or May in Warrington's home country of England.
