#1 Royal Rumble 2008
A sudden injury at the hands of Randy Orton in late 2007 came as a huge blow to Cena.
After holding the WWE Championship for over a year, Cena was forced to vacate, with the Chain Gang leader expected to be out for 6-12 months, meaning he'd miss WrestleMania.

In what is still a shocking feat of perseverance though, Cena rehabilitates his body in record time.
Entering #30 at the 2008 Royal Rumble, everyone inside Madison Square Garden was shocked, from the fans to the commentators to the Superstars themselves.
Last eliminating Triple H, Cena would win his first of two Royal Rumbles (the other being 2013), and whilst fans inside MSG did start to boo him during the match, everyone was on their feet when the iconic Superstar's music hit.
