Jon Moxley will face Kenny Omega at the Aug. 31 All Out pay-per-view at the Sears Centre Arena near Chicago

The build toward the highly anticipated match began at Double or Nothing when Moxley made his AEW debut and attacked Omega following a loss to Chris Jericho.

Moxley vs. Omega will serve as the co-main event on a card that will also feature Jericho facing Adam "Hangman" Page to crown the first AEW world champion.

Moxley beat Juice Robinson in his New Japan Pro-Wrestling debut to win the IWGP United States Championship.

Omega was the first wrestler to hold that title, and if Moxley keeps it throughout the summer, it could play a role in their rivalry leading up to and after All Out.
