UPDATE: CM Punk was backstage at RAW last night but was kept off the show in order to sell his match with The Undertaker. It was announced on RAW by Paul Heyman in a backstage segment that CM Punk will return next week to cut a promo.
ORIGINAL: CM Punk's leg is said to be "really banged up" from his match with The Undertaker at WrestleMania 29 last night.
That being said, he is backstage at RAW. There are rumors that he'll be taking time off in the coming months.
