Tyson, who served three years in jail for rape in the 1990s and who bit off part of Evander Holyfield's ear during a 1997 fight, still thinks he can be heavyweight champion again.
Tyson served time in jail for biting of Evander's Holyfield's ear in the 1997 fight.
It's possible he had jail time from the bite, but also possible he didn't have criminal charges. The system found it hard to determine since he actually did served jail time for rape and mixed it with the assault of the ear.
