How many pro oponents in 46 fights has Joe ever knocked out with this "one punch KO power" you speak of?
The ref stopped it. He lost to Ottke earlier that year aswell. Khan stopped Ortiz Gman beat Jones Jr and Michael Moorer Not that it matters a jot
Yes, he stopped Byrd. It was in 1992, after Chris won the silver medal. http://www.geocities.com/pedrinet/byrd.html
He did not KO Byrd I believe the ref stopped it. Though these spanish geocity links are suspect to say the least (as is wikipedia for obvious reasons).
