Although concussion awareness has become so much better monitored in the sports world, and WWE is no exception, the harsh truth is that being diagnosed with a concussion and having to miss time can really screw up a career. Never is this more evident than with Dolph Ziggler. It's no secret that Ziggler is struggling to stay relevant in the WWE pecking order and despite boasting all apparent skills needed to be a top hand and being extremely popular, Dolph's career isn't what many, including himself, feel it should be. Part of the issue stems from when Dolph became the World Heavyweight Champion in 2013 by cashing in Money in the Bank against Alberto Del Rio. Right before his first major defense at Extreme Rules, Ziggler suffered his huge set back concussion at the prior Smackdown taping. Although he remained champion during his recovery, as soon as returned to face Del Rio he lost the title, causing Ziggler to turn face. Instead of cementing Dolph as a main event player he instead found himself falling back down the card, suffering another concussion along the way. Although Ziggler has proved to be stubborn, unwilling to alter his intense style and talking out of turn on several occasions, most point to his first concussion as the moment his stock in the company fell. While it may not be the most famous wrestling concussion, it certainly might be the most infamous among his many supporters.
