The people involved in the backstage fight at AEW All Out have not spoken publicly about what occurred but one aspect of the story regarding Kenny Omega and Ace Steel appears to have some visual confirmation.
Omega appeared on Capcom TV's live stream to talk about the upcoming Fight Forever video game and as you can see in the screenshot below, his arm is not fully healed after he was allegedly bit by Ace Steel. Per multiple reports, Steel bit Omega in the arm during the melee.
What is next is anyone's guess but the belief is that there will be repercussions after the investigation concludes with potential firings and/or long-term suspensions to follow. Wade Keller recently stated on PWTorch.com that the silence on this issue is expected to break very soon. This could mean that the investigation will wrap up soon and we'll find out what will happen to the parties involved.
