Netflix Fight Night: Mike Tyson to Battle Jake Paul in “Boxing Mega-Event” Streaming Live in July
The streaming giant is partnering with Paul's Most Valuable Promotions on the bout, which will be held at AT&T Stadium in Dallas.
Netflix is getting into combat sports in a major way, picking up what it is calling a “boxing mega-event” that will see the controversial former heavyweight champion Mike Tyson face off against YouTuber-turned-fighter Jake Paul.
Paul’s Most Valuable Promotions is partnering with Netflix on the event, which will stream live on the platform July 20 from AT&T Stadium in Dallas.
The match will be included for all Netflix subscribers (many other boxing bouts still use a pay-per-view model), though tickets will be sold to fill the 80,000-seat arena. There will also be a co-main event and undercard bouts.

I am really not paying attention to RG3's opinion but here is a quick video of Tyson training for the fight. I do think his best shot at winning would be to knock Paul out early.
