John Cena and Sheamus are expected to return at next year's WWE Royal Rumble, reports F4WOnline.com. The current plans call for both former world champions to return at the January event as the major surprise entrants, making it unlikely that other current or former stars will get that opportunity this particular year.
Jake "The Snake" Roberts, for example, who has been talking publicly for months now about being a part of the 2013 Rumble, would most likely sit this one out at the expense of the Cena/Sheamus returns.
The plans could always change between now and then, but this is what's making the waves backstage currently.
John Cena has been in this position before, as he returned early from injury at the 2008 Royal Rumble. Cena went on to win that match and main event WrestleMania 24 later that year.
