A left hook from Spinks floored Johnson, who went down hard and remained on the canvas for sometime, before getting on to his feet on his own.

"I saw the picture-perfect left hook and then I took it. I don't think anybody could throw a better left hook," Spinks said. "Hey, if he got up from that, then I would have quit."
