John Cena and Kane wrestled to a double countout during their match at Royal Rumble 2012. The action spilled to ringside and neither man was able to get back into the ring. Kane gave Cena some chair shots after the match, and then attacked an injured Zack Ryder as well.
When Michelle McCool went in for wrist surgery last month, there were speculations that she was healing up for another run with WWE. However, that does not appear to be the case. No such return is currently being planned right now, as she is spending time with her baby daughter.
