Mexico City:The World Boxing Council has declared the light flyweight champion belt up for grabs. The WBC has stripped Mexico's Omar Nino of the title for testing positive for methamphetamine following a November 18 bout in Las Vegas. American Brian Viloria, currently ranked first in the weight class, will fight second-ranked Edgar Sosa of Mexico for the title, the WBC said. The WBC said the winner will have to defend his title against the 30-year-old Nino. "In light of the fact that the WBC believes that Nino did not voluntarily commit this infraction, and considering that his clean record has won him the trust of this organization. "We are declaring that Nino will be the challenger for whoever is the new champion," a WBC statement said. Boxing regulators in the US state of Nevada suspended Nino in December after he became the first fighter to test positive for methamphetamine in that state. Nino has denied using the drug. Nino (24-2 with two draws) retained the 49-kilo title November 18 with a majority draw over Viloria, the former champion. Nino first won the title with a unanimous decision over Viloria in August in Las Vegas.
