9. Dewey Bozella
â€śWhen you havenâ€™t fought for 21 years itâ€™s kind of difficult,â€ť said Bozella by way of explanation after a rather scruffy win on his pro debut.
The reason Bozella hadnâ€™t fought for 21 years?
He was wrongly imprisoned for murder.
His conviction was eventually quashed and at 52, he resumed â€“ and ended â€“ his boxing career with a pro debut on the undercard of Bernard Hopkins-Chad Dawson 1 in Los Angeles in October, 2011.
