Tyson retired with a 50-6 record and 44 knockouts after losing to Kevin McBride 19 years ago. Paul debuted as a pro boxer about four years ago and is 10-1 with seven knockouts fighting mostly mixed martial artists and journeymen boxers.
The fight was originally scheduled for July 20 but had to be postponed when Tyson was treated for a stomach ulcer after falling ill on a flight. In a documentary chronicling the preparations for the fight, Tyson said he lost 26 pounds in the process of recovering.
During a press conference Wednesday, before the fight, Tyson had terse answers for all the questions asked about the fight asked Paul.
