Former heavyweight champion Mike Tyson and YouTuber-turned-boxer Jake Paul are set to fight in a live boxing match streamed on Netflix Friday, in what would be Tyson’s first sanctioned match in nearly 20 years amid rising concerns about the 58-year-old’s age and safety.

YouTuber-turned-boxer Jake Paul had to wait an extra four months for his high-profile match with 58-year-old former heavyweight champion Mike Tyson.The delay from the original plan for July was caused by Tyson having a medical episode on a plane and needing time to recover from a stomach ulcer,

An early end to the fight between Mike Tyson and Jake Paul favors Tyson, but a longer fight favors Paul. Experts see other possibilities, too.
