He received a lifetime ban from boxing after biting Evander Holyfield's ear. The ban lasted only a year and a half.
In addition to being banned, Tyson was also hit with a $3 million fine for biting off a piece of Holyfield's ear. But he got creative and found a way to pay it off. In 1998, he made an appearance at WrestleMania XIV and was reportedly paid $3 million for his services. He served as a "special outside enforcer" for a WWE Championship match between "Stone Cold" Steve Austin and Shawn Michaels.
