WWE Champion CM Punk recently spoke with Ariel Helwani of MMA Fighting to promote this Sunday’s WWE Royal Rumble pay-per-view and discussed his recent knee surgery, as well as how his knee is doing now and admits that he probably shouldn’t have returned to in-ring action so soon, but noted that he couldn’t take time off at this time of the year, as it is WrestleMania season.

Punk also commented on The Rock, The Undertaker and more in the interview and noted that he may attend the UFC event in Chicago on Saturday night.
