As we reported yesterday here on the website, The Undertaker is expected back on TV shortly, possibly as soon as Monday's Old School RAW.
As of last week, The Undertaker vs. CM Punk was official for WrestleMania 29. At this time, creative is said to be scrambling to fast track the angle, which started with Punk's promo on Monday referring to himself as an "icon" above Superstars and God.
Internally, there is concern with building to the match due to Punk losing two PPVs in a row and then to Cena on Monday. Many feel that the loss to Undertaker at WrestleMania could really damage one of the two names (the other being John Cena) who show they can draw on the road currently.
