On Monday Night RAW, Daniel Bryan formally announced his retirement from the world of professional wrestling. The WWE Superstar first made his decision public on Twitter but elaborated on why to a sold out Key Arena in Seattle, Washington. “The truth is, I’ve been wrestling since I was 18 years old and within the first 5 months of my wrestling career, I’d already had 3 concussions” explained Bryan, who has since incurred many more concussions.
