#3 Uncertainty about Daniel Bryan's health
Daniel Bryan was once told that he would never wrestle again owing to the injuries that he had sustained through the course of his highly successful career. Bryan would visit medical professionals the world over and convince them to allow him to compete once again.
Not only is he back in the roster again, but he is competing at the highest level in WWE with the best in the world. At the same time, we cringe every single time he takes a bump because we know that the worst could potentially come our way when we least expect it to.
Not long ago, we learned that Daniel Bryan was injured after his appearance in WrestleMania 35 and this scared many members of the WWE Universe. Thankfully he is back again, but I wonder if he can pull off a Champion's schedule.
WWE will definitely be careful with Daniel Bryan.
