CM Punk has been absent from both AEW Dynamite and Rampage since his win over MJF at AEW Revolution.

Wrestling Observer Newsletter is reporting that the possible reason for this is because Punk is currently filming the second season of the Starz series Heels.

Filming is expected to last several weeks. 

What is Heels?

Heels is television series created by Michael Waldron that premiered on August 15, 2021, on Starz. In November 2021, the series was renewed for a second season.

"Two brothers and rivals, one a villain, or "heel" in professional wrestling, the other a hero, or "face", play out scripted matches as they war over their late father's wrestling promotion and vie for national attention in small town Georgia."
