WBO super flyweight champion Omar Narvaez (35-1-2, 19KOs) will defend his title against Jose Cabrera (20-2-2, 8KOs) on March 31 in Argentina. The upcoming defense will be the first ring appearance for Narvaez since suffering the first defeat of his pro career, by decision, when he moved up in weight to challenge Nonito Donaire last October in New York City.
