WBO flyweight boxing champion Brian Viloria is finalizing plans to defend his title against nemesis Omar Nino Romero on April 1 in the Philippines, manager Gary Gittelsohn confirmed on Wednesday.

Romero (30-4-2, 12 KOs) handed Viloria (30-3, 17 KOs) his first professional loss, winning a unanimous decision in August 2008 to take Viloria’s WBC light flyweight title.

The two fought a rematch in November of that year, with Romero winning a close majority decision. The bout was later ruled a no-contest after Romero failed a postfight drug test. Since then, Viloria has won two world titles, stepping up in weight to defeat Julio Cesar Miranda last July for the WBO flyweight title.

He successfully defended the belt with the biggest win of his career, dominating Giovanni Segura in an eighth-round TKO in December.

Gittelsohn said he will try to have the fight shown live in Hawaii.

"We will endeavor to make arrangements to offer the broadcast locally in Hawaii," Gittelsohn wrote in an email to the Star-Advertiser. "Our mission is to prove that Brian is the greatest of the ‘little giants.‘ "

The fight takes place on a Sunday in the Philippines, but would be shown live on a Saturday night in Hawaii.

Viloria is the No. 3-ranked 112-pound fighter, according to Ring Magazine, after his dismantling of Segura, who at the time was the No. 9 pound-for-pound fighter in the world. Viloria was up 70-63, 69-64 and 68-65 on the three judges’ scorecards at the time the fight was stopped.

Romero hasn’t fought since his second run as WBC light flyweight champion ended in a decision loss to Gilberto Keb Baas in November of 2010. Romero is scheduled to fight Sammy Gutierrez next Saturday in Mexico, and a victory would ensure the fight with Viloria takes place.
