It appears that there may have been a secondary reason why John Cena missed Raw this week. There have been several reports, confirmed by WWE.com and Cena himself, that he has suffered a torn rotator cuff, which will require surgery and keep Cena out at least 6-9 months. This means that Cena will definitely miss both the Royal Rumble and, more importantly, WrestleMania. Cena joins a list of injured WWE main event stars set to miss WWE’s biggest show, including Randy Orton, Seth Rollins, and Daniel Bryan.
