He said: “Marcus McDonnell was the referee, and it was 116-113. It was one of them fights – in my first 12 rounder – where by about round seven I was absolutely blowing.”
“I was thinking, this guy, I can’t hurt him; I’d hit him with my best shots and he just stood there. He was a solid, solid geezer from Ghana, solid as a rock, like a tree actually, a big oak tree.
“I was hitting him with shots and he just wouldn’t budge. I was tiring, starting to doubt myself, he was coming on strong as well and, in round eight, Rob McCracken said to me ‘go back at him; when you’ve done your attack, go again.’
“I threw a double-jab right-hand after I’d already attacked him and dropped him, so he went down on one knee. It was like the Rocky 4 moment when he cut Ivan Drago.”
