On this week's edition of Being the Elite, Matt and Nick Jackson formally accepted the challenge. The match will be for those AAA World Tag Team belts.
The Bucks won the belts from Pentagon and Fenix (who themselves had just won them from Los Mercenarios) on March 16 at AAA Rey de Reyes. The Lucha Bros failed to regain them at Double or Nothing on May 25, but ultimately won the titles back on June 16, at AAA's Verano de Escándalo.
The card for All Out now has five matches:
-To determine the first AEW World Heavyweight champion: Chris Jericho vs. Adam Page
-AAA World Tag Team/ladder match: The Lucha Bros vs. The Young Bucks
-Jon Moxley vs. Kenny Omega
-Cody Rhodes vs. Shawn Spears
-Best Friends vs. The Dark Order (winners receive a bye in the AEW World Tag Team title tournament)
