“I’m on cloud nine right now. This is the twentieth fight of my career and I told a few of my close friends I was ending it in the second round,” Harris said following the fight, via the New York Post. “I knew in the first round when I dropped him a couple of times, I knew that with each punch it was getting easier.

“I am willing to fight anybody, anytime, anywhere whether it’s MMA or bare knuckle. So anybody that thinks they want to shut my mouth, they come and get it.”

As for Vistinte, the knockout was enough for him and he’s decided to call it a career.

“It was a good run. Had my first professional fight at 16. I loved every minute of it. It’s took me too long to realize that the dream of my children and family are more important than mine alone,” he wrote in a statement on Twitter. “It’s been real guys. I love every single one of y’all who have supported me. Thank u”
