#1 John Cena loses and calls it a day...for now

Undertaker vs. John Cena! The Cenation leader's teasing promo on Raw has rekindled the hopes of the match finally coming to fruition. While the fans may have been given a straightforward message from Cena himself that it may not happen, it could all be a part of the eventual confirmation.
And then you have reports of Cena wanting to have a match with Rey Mysterio or Samoa Joe if the latter manages to recuperate from his injury in time. The options are aplenty for the 16-time World Champion as he prepares for a six-pack title match at the upcoming Fastlane PPV.
Look who just shut down all of Tony Khan's critics! More HERE.
Heck, Cena vs. Nakamura vs. AJ Styles for the WWE Championship at WrestleMania sounds plausible now that Cena is a part of the Fastlane proceedings.
While Cena losing in a triple threat match or to Samoa Joe wouldn't be an upset in any way whatsoever, putting over Undertaker and Rey Mysterio would absolutely be a surprise.
The 40-year-old 'free agent' is expected to resume his Hollywood duties once WrestleMania is wrapped up and we're sure he would want to leave a lasting impression until his eventual return.
