Mike Tyson and Henry Cejudo mix it up in AEW pro wrestling brawl with Chris Jericho - ESPN

In the AEW segment, Tyson walked to the ring flanked by several big names from the MMA world, most notably former UFC two-division champion Henry Cejudo.

Two days earlier, the UFC announced that Cejudo was considered retired, and his bantamweight title was vacated.

Cejudo was involved on Tyson's side in the storyline brawl against Jericho's faction.

Tyson appeared Saturday night at AEW's Double or Nothing pay-per-view event, awarding the new AEW TNT championship belt to title winner Cody Rhodes.
