Did you know that every single WWE superstar who walked out of last years WrestleMania as champion are currently out of action due to injury? Did you also know that the majority those superstars, if not all of them, are likely to miss this years WrestleMania, too? WWE are hoping to break attendance records with this years WrestleMania, but you have to wonder whether the thirty second instalment of the event will fail to deliver due to so many big-name performers being confined to the bench. While it is possible for a few of these performers to return in time for the biggest show of them all on April 3rd, its clear that their inactivity will effect the show's buildup and will also alter what role they will be able to play at the Grandaddy Of Them All. So much is up in the air heading into WWE's biggest event of the year, which also happens to be one of their biggest events ever, with a potential 100,000 spectators looking on. Here are 7 WWE superstars whose absence over the next few months will alter, for better or worse, the entire year. For WWE's sake, let's hope this injury crises is over. At this rate, we might end up with Heath Slater versus Ryback going closing the show in Dallas!
