***** THIS IS A RUMOUR, TAKE WITH A GRAIN OF SALT
There have been numerous reports that Daniel Bryan has a major concussion and it came from his match at against Sheamus on Smackdown post Wrestlemania. IF this is true, it has the potential to be career threatening for Daniel Bryan. This would make sense that Bryan's injury has not been specifically stated as to what exactly it is. Most likely trying to keep the details of a concussion to their biggest star under wraps as they go through concussion lawsuits.
If this is true, we may never see Daniel in a ring again. This is a scary thought considering how talented and fun to watch he is. I personally am hoping for the best case scenario here, one that allows him to compete again, without doing further harm to his body. As much as I love him in the ring, it would be more tragic for me to see him do some permanent damage to himself because he didn't know when to hang up his boots.
