Ivan "Iron Boy" Calderon, junior flyweight champion of the World Boxing Organization (WBO), will unify his title with the champion of the World Boxing Association (WBA), Mexico's Giovanni Segura, on the 28th of August at the Coliseo Mario "Quijote" Morales in Guaynabo, Puerto Rico and will be broadcast on "Pay Per View" under a promotion of PR Best Boxing Promotions (PRBBP).

Calderon (34-0-1 and six KOs), former WBO champ at 105 pounds, will present his belt for the seventh time at 108 pounds against Segura, a strong puncher with a record of 24-1 and 20 knockouts.

In a recent interview with the newspaper Primera Hora, published Tuesday, Giovani Segura gave Calderon praise, but says that he has studied his opponent and will not make any costly mistakes.

"Many have underestimated him. Calderón's success has not been because his style, but because of his intelligence and experience, which is how you take control of the fight," Segura said. "Logic says that Calderón will try to dodge my shots, so for his style of boxing I will have to cut off the ring ... I'm in a similar situation."

"Everyone says you should try to box against me because I dont have a lot of experience, but once you get hit, things are different ... Calderon has a quick style, plus he's smart and knows how to get out of distress. This fight will be about more than my punch, it will be a battle of intelligence. Whatever I know about boxing, I will try to implement it."
