According to Fightful, Young Bucks & Kenny Omega were extremely pissed off about Punk’s comments during All Out Media Scrum, and one talent that Fightful heard from claimed that the EVPs were threatening to leave the company.
Bryan Alvarez also seeming confirmed that there was an physical altercation backstage:
"Apparently there was an altercation after Punk left the press conference.
He was obviously very mad, and we had multiple, multiple sources state that there was an altercation.
I wasn’t there, I don’t know everything that happened, but many people said that there was an altercation with Punk and the Young Bucks.
I don’t know who else was there, but it happened, and everybody knew about it, and a security guard did in fact go running out of the press conference."
