Daniel Bryan was riding as high as someone can coming out of Wrestlemania 30. He won the WWE World Heavyweight Championship at Wrestlemania beating HHH, Orton, and Batista over the course of 2 matches. And On Smackdown after WM30 he was endorsed by WWE Hall Of Famer and Legend Hulk Hogan. Then He had his match with Kane at Extreme Rules and everything changed for him. After the match he went to the doctor and found out he had to have neck surgery. The injury was cumulative from years of stress and damage that he puts his body under due to his style of wrestling.
