The reported incident took place at Jimmy's Famous Seafood in Baltimore, where a birthday celebration was being held for announcer Tony Schiavone.
From Haynes' initial report: "I was told that at some point during the altercation Jimmy Havoc threw a punch at Excalibur, but missed. Which led to Excalibur putting Havoc in a choke hold that put him to sleep. Atlas security stepped in and got Excalibur to release the choke hold, however the incident was not over because when Havoc came to he once again throws a punch at Excalibur only this time he connected. This resulted in a skirmish/brawl/pull apart between the two, until Atlas security could break it up and escort Jimmy Havoc outside.
"Once outside, a member of Atlas security was attempting to calm an intoxicated Jimmy Havoc down, but this was interrupted when Excalibur came outside to try and talk things out. Jimmy was still upset and was not wanting to talk and was said to have thrown his cell phone in the direction of Excalibur, missing him but not the wall as his phone broke into pieces. Security again separated the two sending Excalibur back inside while they waited for an uber to pick up Havoc and take him back to the hotel."
Haynes' report notes that Havoc ended up being "remorseful" about the situation, and he and Excalibur later calmly settled things.
AEW President Tony Khan was asked about the incident during the post-Full Gear scrum early Sunday morning and said, "I wouldn't call it a fight. I've seen a lot worse in the world of football, both in England and the NFL. I've seen a lot worse, and I saw a lot worse tonight. They scrapped around and it was cool yesterday, it was cool today. It's fine."
