The WBO flyweight championship fight between Anthony Olascuaga and Jonathan Gonzalez at the Airake Arena in Tokyo, Japan ended after just 2:25 of the first round following a clash of heads.

The action was warming up before the fighters leant into one another and their heads collided, leaving “Bomba” Gonzalez with a cut by his left eye.

Southpaw Olascuaga, from Los Angeles, California, was clearly frustrated and is now 7-1 (5 KOs) 1 ND. Puerto Rico’s Gonzalez is 28-3-1 (14) 1 NC and 1 ND.
