CM Punk Undergoes Surgery, Out At Least 8 Months

According to Wrestling Observer's Dave Meltzer, the injury occurred rather early on in the match against Moxley. It happened when Punk attempted a tope suicida to the outside on the Blackpool Combat Club member.

"CM Punk underwent surgery earlier this week for the torn left triceps he suffered when doing the tope early in the Jon Moxley match. That is usually about an eight month recovery period. His doctor recommended surgery right away to prevent any muscle atrophy," Meltzer said.

As Meltzer said, his injury carries an eight-month recovery period. This caused the AEW World Championship to be vacated for the first time in its history.

AEW owner Tony Khan announced a "tournament of champions" to crown a new World Champion at AEW Grand Slam on September 21. The tournament final will be decided this week. Chris Jericho takes on Bryan Danielson, while Sammy Guevara will face the former champion Moxley.

Had Punk not been injured, the title still likely would have been vacated. After All Out, Punk launched into a fiery tirade. He buried former friend Colt Cabana, Hangman Adam Page, and The Elite right in front of Khan and the entire world.

Following this tirade, Punk reportedly got into a physical altercation with The Elite in his locker room. The Elite allegedly confronted Punk, and Punk allegedly threw the first punch at Matt Jackson. Matt's brother Nick was hit with a steel chair in the eye and was knocked out.

Punk's trainer and friend Ace Steel allegedly threw the chair. Furthermore, he reportedly bit Kenny Omega and pulled his hair.

Punk, The Elite, Steel, Christopher Daniels, Michael Nakazawa, Pat Buck, and Brandon Cutler all received suspensions in the wake of the fight. A third party is conducting an investigation into the incident.

"Neutral" parties are being interviewed as a result. Among the most important witnesses include AEW's chief legal officer Megha Parekh and MJF, who made his return to AEW at All Out.

Steel is allegedly set to be fired once the investigation concludes. However, Punk's status remains up in the air. Reports indicate the feeling is the Straight Edge Superstar will be done with the company soon.

According to Fightful Select, the AEW locker room is "more anti-CM Punk than it ever has," and "major amends" would need to be made if Punk were to return to the company.
