Top Rank big boss Bob Arum told Fightnews on Wednesday that Filipino champion Nonito Donaire will relinquish his IBF flyweight crown to vie for the soon-to-be-vacated WBA super-fly title on Aug. 15 at the Hard Rock Hotel in Las Vegas. In the main supporting fight, another Filipino puncher, featherweight Abe Concepcion battles Steven Luevano for the world 126-lb crown. This fight was originally scheduled May 2 underneath the Manny Pacquiao-Ricky Hatton scuffle but an injury suffered by Luevano prompted Arum to call it off.
In another development, Arum revealed that Brian Viloria will defend his IBF light-fly diadem sometime in September in Cebu City in the Philippines where the Hall of Fame promoter said Rodel Mayol might get his immediate rematch against Ivan Calderon of Puerto Rico for the WBO light-fly jewels following the disappointing result of their bout over the weekend at Madison Square Garden.
