WWE.com has posted an update on the medical condition of WWE Champion CM Punk, however as with all things that come out of the WWE, take it with a huge grain of salt:
"As WWE Champion CM Punk’s potential title defense against Ryback approaches on the Jan. 7 edition of Monday Night Raw, WWE.com sources indicate that The Straight Edge Superstar has been medically cleared for in-ring competition several weeks after his undergoing knee surgery. The decision, if confirmed, returns Punk to action effective immediately, meaning he will defend his championship as scheduled in a Tables, Ladders & Chairs Match against Ryback."
The article indicates that confirmation will be given during tonight's episode of WWE Main Event.
