UFC Louisville main event winner disagrees with controversial stoppage

UFC Louisville was headlined by a middleweight clash between Jared Cannonier and Nassourdine Imavov.

Cannonier was up 2-1 after three rounds according to many who watched the fight, but during the fourth round, was caught with a sharp right-hand counter by Imavov. 'Tha Killa Gorilla' was wobbled by the strike, but remained on his feet.

As 'The Sniper' continued to unload punches onto his hurt opponent, the referee Jason Herzog intervened and called the fight off. But there were cries from fans and fellow fighters that Herzog had stopped the bout too soon.

However, the surging middleweight contender did not agree, as he appeared in front of the media after his victory and said this:

"Absolutely not [an early stoppage]. It's the job of the referee to decide if the fighter in able to keep going or not. He already took a lot of damage, he would have taken even more if the fight continued. So I think it was the right decision."
