As we previously reported, Mike and Roy will headline a pretty stacked card featuring some pretty interesting fights ... including Nate Robinson vs. Jake Paul and Badou Jack vs. Blake McKernan.
Also, Viddal Riley -- the fighter who trained KSI for his fights with Logan Paul -- will take on ex-UFC fighter Rashad Coulter.
The event will air on the Triller app and via Pay-Per-View. It's also the first in a series of events for Tyson's new Legends Only League, founded by Mike, Sophie Watts, Johnny Ryan Jr. and Eros Innovations -- which will feature some of the greatest athletes of all time getting back into competition.
The California State Athletic Commission had cautioned fans that the Tyson vs. Jones fight was going to be more of a show than a real fight ... but both Mike and Roy have said the goal is to take each other out.
"This is search and destroy and I’m looking forward to recapturing my glory," Mike told us earlier this month.
"The fighting game is what I'm about and hurting people is what I'm about."
