GUAYNABO, PUERTO RICO - Filipino fighter Bernabe Concepcion trained this afternoon at the Wilfredo Gomez Gym before traveling to the United States to complete their preparations en route to his commitment of July 10 on the event "The Challenge" when he challenges the champion at featherweight of the World Boxing Organization (WBO) Juan Manuel "Juanma" Lopez, to be held at the Coliseo de Puerto Rico. A presentation of Top Rank and PR Best Boxing Promotions.

Concepción worked in warm-up exercises, shadowboxing, hit the bag, jumping rope, sweating quite a bit in the company of his agent Michael Koncz.

"We're doing something to keep fit, but when we travel, we will work hard to fight back in America," said Concepcion, who has only 22 and has to defeat Puerto Rican Mario Santiago in February.

The fight between Lopez (28-0, 25 KOs) and Concepción marks the return of the U.S. network Showtime on the island. Tickets, which can be purchased at the Coliseum Box Office or Ticketpop Puerto Rico by calling (787) 294-0001, cost $ 35, $ 50, $ 75, $ 150, $ 200 and $ 400.
