Many fans were confused when Sheamus was removed from the main event of Sunday's Survivor Series. The reasoning behind the decision became clear on Thursday. It was revealed the Irishman suffered an arm stinger in addition to other neck and spinal injuries on Monday's Raw. Mark Henry delivered the World's Strongest Slam to Sheamus through a table, which is likely when the problems occurred. The Celtic Warrior tweeted this picture from a hospital bed, seemingly moments before he had the required surgery. Sheamus has had back luck recently when it comes to injuries. He picked up a torn labrum in his left shoulder in August 2013 and was out until the Royal Rumble in January. Now, less than a year after his return, he will likely remain on the shelf for the foreseeable future as a return date is unclear.
