Former two-time world champion Ivan "Iron Boy" Calderon has new opponent in place. Calderon returns on October 29 at the Coliseo Mario "Quijote" Morales in Guaynabo, Puerto Rico. Earlier this week, a hand injury forced Raul "Rayito" Garcia to withdraw as Calderon's opponent. The card is presented by PR Best Boxing Promotions (PRBBP) as part of the 24th WBO Annual Convention.

Now, Calderón (34-2-1, 6 KOs) will face Mexican Felipe Rivas (11-8-1, 5 KOs) for the 105lb WBO Latino title.

As reported on BoxingScene.com on Wednesday, Carlos "El Indio" Quintana (28-3, 22 KOs), the former WBO welterweight champion, was also forced to withdraw from his scheduled fight after suffering a nose injury in a sparring session. Quintana was supposed to face hard puncher Jorge "Destroyer" Meléndez (20-2-1, 20 KOs) for the WBO Latino junior middleweight title. A rival for Melendez will be announced soon.

In the co-featured fight, former WBO superbantamweight champion Wilfredo Vázquez Jr. (20-1-1, 17 KOs), will fight for the WBO 122lb Intercontinental title against a foe to be named, and Argentinian Yessica Yolanda Bopp (16-0, 7 KOs) will defend her WBO junior flyweight belt against Suzane Warner (9-10-1, 2 KOs) in a 10 round bout.

In another title bout, Javier Monserrate (24-1-1, 17 KOs) and Javier Castro (25-4, 20 KOs) will fight for the WBO Latino junior welter belt.

In four rounds bouts, Israel “El Heredero” Vázquez (3-0-2, 3 KOs) versus debutant Jesús Pagán in the flyweight division; Kenny Rivera (1-0, 1 KO) will face Leduan Barthelemy (2-0, 2 KOs) in the featherwight division, and debutants Anaury Rijo and Pablo de Jesus will fight in the junior middleweights.

The 24th WBO Annual Convention is from October 24 to October 29 at the Ritz Carlton Hotel in Isla Verde, Carolina, Puerto Rico.
