Former heavyweight champion Mike Tyson will return to the boxing ring for an exhibition fight against ex-four-weight world champion Roy Jones Jr.
The bout is scheduled to take place on 12 September in Los Angeles.
Tyson, 54, last fought professionally in 2005 when he was beaten by Irishman Kevin McBride in what was his sixth loss in 58 career contests.
Fellow American Jones, 51, has not fought since beating Scott Sigmon in February 2018.
The California State Athletic Commission has sanctioned the fight, which will be over eight rounds and broadcast on pay-per-view.
Tyson became the youngest ever world heavyweight champion at 20 when he knocked out Trevor Berbick in 1986.
He recently fuelled rumours of a comeback when he shared filmed pad workouts on social media.
In 2006, Tyson had a number of four-round exhibition bouts with Corey Sanders. At the time he needed money having filed for bankruptcy in 2003, but he also spoke of the mental health and stress-relieving benefits a light-hearted return gave him.
More recently, there had been talk of Tyson fighting former rival Evander Holyfield, who retired in 2014.
Holyfield, 57, won their two previous bouts in the 1990s, including the infamous encounter in 1997 when Tyson was disqualified for biting his opponent’s ear.
Jones Jr claimed world titles at middleweight, super-middleweight, light-heavyweight and heavyweight during his career.
“It’s like David and Goliath,” said Jones Jr in a promotional video.
I actually think there will be ridiculous amounts of interest. There shouldn’t be, but there will be.
Only two years ago, Roy Jones Jr won a version of the world title. He has pushed on for too long. Mike Tyson fought from memory for the last four or five years of his career.
This is about testing the water to see if they can actually get something the organisers call the “Legends League” off the ground. It’s about seeing how competitive it is.
I’m sure it’s entertaining to a degree, but it’s crazy.
