Mike Tyson might have missed out on the modern-day equivalent of a nine-figure sum during his rematch with Evander Holyfield in June 1997.
On the 23rd anniversary of the bout, Action Network's Darren Rovell estimated the disqualification and its subsequent fallout cost Iron Mike around $100 million or more.
Tyson had to forfeit $3 million from his $30 million purse and received an 18-month ban.
Forbes estimated Tyson's career earnings to be as high as $685 million.
