The legal adviser for Celestino Caballero, Rogelio Espiño, has sent an offer to Osvaldo Rivera, the promoter for WBA "regular" featherweight champion Jonathan Victor Barros. Caballero and Espino have no problem with the proposed date of June 4. They are attempting to bring the fight to the Arena Roberto Duran in Panama. They know the task won't be easy. Caballero is Barros' mandatory challenger.

"We made the offer and now we're waiting for response from them, but we know that it won't be easy to bring that fight to Panama," said Espino to Victor Ortiz. "Anyway, we made a very good financial offer to Barros, but we believe they will make a counter-offer. If they make a counter-offer, we'll have to analyze it."
