#2 Injury risk

Whether fans want to admit it or not, Daniel Bryan is at an immense risk for another concussion if he steps into the ring even one more time. Of course, if WWE is actually going to put him in the ring for one more match, they will probably do everything in their power to protect him, but even that might not be enough.
In the end, Bryan's health and happiness should be at the forefront of his and his fans minds when considering the idea of coming back for one more match. Keep in mind that after the match is over and the fans yell their last yes chant in honour of The Bearded one, Bryan will have to live with the consequences of that match for the rest of his life!

Is that really worth it? Is it really worth one more round of yes kicks and a timely Yes Lock if Daniel Bryan gets injured again and has to live with it for the rest of his life? Think about it! The man has a family that he needs to support a wife he wants to spend his golden years with and a child that he wants to be there for.
A match at this point in his life just isn't worth it.
