WBO super fly kingpin Omar Andres Narvaez returns to action tonight at the famed Luna Park Stadium in Buenos Aires, Argentina.
Narvaez, 34-0-2 (19), will be looking to retain the 115 pound crown for the third time after he graduated from a seven year reign as WBO flyweight champion.
The 35 year old Cordoba based southpaw will face the challenge of a much younger rival, Colombian slugger William Urina, 17-1 (14).
The 25 year old from Barranquilla is coming off a loss to Johnny Garcia for the WBC Fecarbox strap in January, in which both men had to climb off the canvas before Garcia won a decision and Urina's WBO Latino title.
Urina has vowed to bounce back however and believes he has the punch to bother the champion, who is coming off a successful points defense in April against previously undefeated Cesar Seda.
Narvaez has won 20 straight bouts since being held to a draw by Andrea Sarritzu in 2003 and "El Huracan" is the clear favorite in this one.
Several interesting contests are on the undercard, the best of which is a WBA/WBO flyweight title tilt between champion Yesica Yolanda Bopp, 15-0 (6), and hard-hitting Mexican challenger Yesenia Martinez Castrejon, 9-6 (8).
Undefeated super flyweight Roberto Domingo Sosa, 20-0 (12), takes on Santiago Ivan Acosta, 17-7-2 (7), while welter Hector David Saldivia, 37-2 (30), faces Carmelito De Jesus, 14-2 (11), both bouts scheduled for six rounds.
