WWE.com has updated the medical status of WWE Champion CM Punk:
“CM Punk underwent knee surgery today to remove a piece of torn meniscus that had locked up his knee. The surgery, performed by Dr. James Andrews, went smoothly and CM Punk is expected to make a full recovery.”
ProWrestling.net is reporting that the feeling among several WWE employees is that Punk has been working through injury, and is expected to continue working through pain for the upcoming TLC pay-per-view.
It is worth noting that WWE.com previously explained Punk's injury as the result of Ryback's assault on him last night during the main event segment of Monday Night Raw. So it's very possible that WWE is just posting a generic response to Punk's surgery, and its actual result is still completely unknown.
