The Royal Rumble pay-per-view is less than a month away, and it's anybody's guess who wins the 30-man battle. But there may be one major name you can scratch off the list, according to WrestleVotes:

If that's the case, then John Cena - whom SkyBet lists as the favorite to win the Royal Rumble with 5/2 odds - will not be headlining WrestleMania 34. The 16-time World Champion won the event in 2008 and 2013, but it'd be surprising if he were to win a third given he's reverted to a part-time wrestling role.

With Cena seemingly unlikely to win the show, the field appears to be much more open. Dean Ambrose is sidelined long-term with an elbow injury, which takes two major names out of the running. Roman Reigns may become the new favorite, given the undying rumors of him facing Brock Lesnar on the Grandest Stage of Them All. Finn Balor could be another choice, but Vince McMahon doesn't yet believe he is "over enough."

It's not shocking that Cena reportedly won't win the event. The 40-year-old has battled numerous injuries, and is barely two years removed from shoulder surgery. Cena has helped pass the torch to younger performers like Shinsuke Nakamura, AJ Styles and Reigns, so it doesn't make sense for the part-time wrestler to win the youthful talent on the roster.

And with part-timer Brock Lesnar questionably holding onto the Universal Championship for nine months, it wouldn't make any sense for the creative team to move forward with aging superstars once again. It's a new era of wrestling, and Cena has already hinted at possibly leaving WWE in the future as he builds up an acting career.

We'll see if more develops from this report, and if a new favorite over Cena emerges to win the Royal Rumble. Nakamura or Braun Strowman, anyone?
