John Cena is one of the most protected Superstars in WWE history - thats no secret. The writers go to incredible lengths to preserve both the brand and the standing of the face of their company, so much so that Cena has been pinned on just four occasions in the last 2 yearsand two of those defeats came after interference from the Wyatt Family. But despite this kind of mollycoddling, Cenas record hasnt always been so formidable. Naturally, over the course of a 12-year career, hes suffered a number of high-profile defeats. You dont get to become a 15-time world champion without losing a fair few along the way. Well, at least 15, I guess. More specifically though, some of these losses have been rather out of the ordinary for a man of Cenas stature. While its understandable for the Randy Ortons, CM Punks, and Daniel Bryans of this world to grab the odd victory over the Leader of the Cenation, plenty of his conquerors have been a million miles from that kind of level. On the other hand, some of the losses have been so one-sided that youd struggle to believe that they involved a man who has achieved so much with the WWE. One thing they all have in common though, is that theyve tended to be downright embarrassing for Cena. This article looks back at each of the defeats hes sustained over the years, picking out the seven most embarrassing instances that will forever blemish his otherwise-perfect resume.
