F4WOnline is reporting that current creative plans could see WWE Champion CM Punk defeating the Rock at the upcoming Royal Rumble in their highly anticipated match, and going on to face the Undertaker at WrestleMania 29 with the championship on the line.

One major reason WWE is hesitant to put the belt on the Rock going into WrestleMania, is the lack of title matches at house shows between January and April, as well as the company's Elimination Chamber pay-per-view.

According to the report, the WWE's concern for house shows is also a big reason they have not unified the two major World titles, as they feel a championship match should ideally close out each local event.

Wrestlezone will have more on this report and all WWE news leading into the 2013 Road to WrestleMana as it becomes available.
