As noted earlier, CM Punk is currently taking some time off to address several nagging injuries, as well as to allow his injured knee to heal. There were reports that Punk may be off until around SummerSlam, however WWE is advertising Punk for several events this summer.
WWE has removed Punk from all RAW tapings before May 13th. He is currently scheduled to appear at the May 13th RAW taping, and most of the following RAW tapings throughout the summer. Also, while he is not listed for the Extreme Rules pay-per-view on May 19th, he is appearing on the event screens on WWE.com for the Payback, Money In The Bank and SummerSlam pay-per-views.
Punk has also been removed from most RAW house shows. However, he is advertised for the RAW overseas tour in Japan and Australia in early July.
