In July 2011, Kovalev won his first NABA belt in a 10-round fight with Douglas Otieno from Kenya. The Russian’s next bout against Grover Young was controversial, however, as in the second round, Kovalev threw a left hook to the head, but the judges suggested that it was a blow to the back of the head -– an unintentional infringement. And as the American could not continue, the fight was declared a technical draw.
