According to a report by The Wrestling Observer, WWE officials are not aware of a “firm timeline” for when WWE Champion CM Punk will be returning to the ring following surgery on his left knee on Tuesday to remove a piece of torn meniscus. No estimates will be made public until Punk begins rehab on the knee. The belief is that an estimate could be known within a few days. As confirmed on Tuesday evening by WWE, Punk has been pulled from the TLC PPV on 12/16.
