Tyson will face former four-weight world champion Roy Jones Jr in an exhibition bout in Los Angeles.
The event was scheduled to take place on 12 September but will now be on the 26 November.
“Changing the date will give more people the opportunity to see the biggest comeback in boxing history,” Tyson said.
Mike Tyson last fought professionally in 2005 when he was beaten by Kevin McBride in what was his sixth loss in 58 career contests.
Jones has not fought since beating Scott Sigmon in February 2018.
The California State Athletic Commission has authorized the fight, which will be over eight rounds and broadcast on pay-per-view.
