#3 Alex Riley accidentally gets eliminated - WWE Royal Rumble 2011
Alex Riley was being pushed as a heel Superstar by WWE in 2011. He had the potential to be a star, and he was getting a lot of exposure as The Miz's sidekick.
During that year's Royal Rumble match, which was the largest at that time with 40 participants, Alex Riley was booked to eliminate John Cena from the match.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
Unfortunately for Riley, he eliminated himself by falling out of the ring while being beaten up by Cena and Kofi Kingston in the corner. The Leader of the Cenation was left stunned that the person who was supposed to eliminate him... got eliminated.
Thankfully, WWE managed to develop a new plan by having The Miz, who was the WWE Champion at that time, interfere in the match and toss Cena over the top rope.
At WrestleMania 27, John Cena challenged Miz for the WWE Championship, but he failed to capture the title after The Rock cost him the match.
Meanwhile, former WWE star Alberto Del Rio won the 40-man Royal Rumble match and lost his World title match at WrestleMania against The Rated-R Superstar Edge.
