WBC light heavyweight champion Oleksandr “The Nail” Gvozdyk, 17-0, 14 KOs retained his title via the strange stoppage of Doudou Ngumbu, 38-9, 14 KOs on Saturday night at the 2300 Arena in South Philadelphia.

Gvozdyk was well ahead on the cards leading to the stoppage which witnessed the challenger abruptly pull back in the fifth, complaining about an injury to his right calf. The ringside physician, the fighter and his corner briefly talked before the fight was waved off in a rather quizzical ending.

“It wasn’t what I expected, but I did my best,” Gvozdyk said. “Sometimes this happens in the sport of boxing. It is what it is.

“My goal is to unify titles. I will wait to see what my team tells me to do next.”

On the nights undercard, Welterweights Ray Robinson 24-3-1, 12 KOs, and Egidijus Kavaliauskas, 21-0-1, 17 KOs, fought to a 10-round majority draw.

The heavy underdog for the contest, Robinson wisely kept the hard hitting Kavaliauskas on the outside by using his jab and reach to win rounds which was enough on one scorecard to win the contest 97-93, not so on from the other two judges who was unable seperate them as they rendered scores of 95-95.
