Batista won Royal Rumble 2014 by eliminating Roman Reigns in the end. Other contestants during the match were Alberto Del Rio, Alexander Rusev, Antonio Cesaro, Big E Langston, CM Punk, Cody Rhodes, Damien Sandow, Dean Ambrose, Dolph Ziggler, El Torito, Erick Rowan, Fandango, Goldust, Great Khali, Jack Swagger, JBL, Jey Uso, Jimmy Uso, Kane, Kevin Nash, Kofi Kingston, Luke Harper, R Truth, Rey Mysterio, Ryback, Seth Rollins, Sheamus and the Miz.
While we still do not have a definite answer as to how long he has been upset with the company, we do know now that CM Punk was already contemplating a departure from WWE as early as Royal Rumble 2014. He vented to Mick Foley at the time about not being happy within the company and having trouble dealing with injuries.
After he was pulled from Royal Rumble 2014 at the last minute, Evan Bourne told fans on Twitter that he was still working on making his return to WWE, but as of right now, it does not appear that management is making that a priority backsage.
Since the company wanted to sell the brutality of Brock Lesnar for his match against Big Show at Royal Rumble 2014, they had Mark Henry work an injury angle and take a couple of weeks off. It looks the former world champion is returning to WWE, possibly as soon as Monday Night Raw this week.
