The big story in the WWE at the moment focuses on the WWE World Heavyweight Champion, Daniel Bryan. He has been forced to undergo neck surgery due to a troublesome injury, and looks set for a significant period on the sidelines - leading to speculation whether he will be able to continue as the main champion in the company. There is a seriously realistic possibility that Daniel Bryan will be stripped of his WWE World Heavyweight Championship, and forced to vacate the belt. That may seem harsh given the popularity he has at this moment in time, but the company has a duty of care to keep the championship relevant and interesting. However, even if Bryan is forced to vacate the championship, it wouldn't be the first time it has happened in the history of the company. Daniel Bryan will not be the last champion that vacates if that turns out to be the case, and he certainly hasn't been the first. It may cause a huge stir amongst wrestling fans if Bryan has the belt taken off him, but that could eventually lead to a huge storyline when he returns from his injury. Down the years, there have been a whole host of instances where champions have been forced to vacate their championship for a number of reasons. It could be due to a legitimate injury that has forced them out of action, or it could be due to a storyline development that causes huge controversy and heat on the guys in question.
