Daniel Bryan did not have the best of times during his first stint in WWE. However, his return turned out to be great for the company and the superstar. The underdog superstar slowly became known as one of the best in-ring workers in the world.

His popularity and skills helped him gain the backing of the WWE Universe. At WrestleMania XXX, The Yes Man competed in two epic battles to become the new WWE World Heavyweight Champion. However, somewhere during the two matches, Bryan aggravated his neck injury that took him out of competition for some time.

“I was supposed to only be out for about six to eight weeks after surgery, but what happened when I hurt my neck was that the nerve was compressed and for a long time it was just sending shooting pain down my arm," Bryan continued. "The pain wasn’t really a problem, but it became an issue when it became weakness, and when I couldn’t even unlock my car door."

“So that’s when they decided that I needed the surgery and it couldn’t wait any longer. But then we did the surgery and there was an issue as the strength wasn’t coming back, and there was thought that perhaps the nerve had been compressed too long, that I’d waited too long to get the surgery. I’ve been wrestling a long time, had a lot of stuff happen to me but never really got it taken care of, so I thought it was all coming back to bite me!” Bryan revealed.

Bryan made an unexpected return to the ring after the injury. Things did not go too well for The Yes Man, as he suffered a concussion in the ring during an Intercontinental Championship ladder match at WrestleMania 31.

Due to medical reasons, effective immediately, I am announcing my retirement. Tonight on Raw, I'll have a chance to elaborate. #gratitude
