10 Unbelievable Royal Rumble Moments

#3 John Cena's surprise return

John Cena's entrance in the 2008 Royal Rumble stunned the world.

Many fans believed John Cena would miss nearly a year of action in 2008 after he announced a serious pector injury. It seemed as if Big Match John's scheduled return would take place well into the next year, meaning he would miss both the Royal Rumble and Wrestlemania.

Then something shocking happened. The lights went low, and then suddenly standing in the entrance ramp at the 2008 Royal Rumble was John Cena himself. Though his original prognosis was grim, Cena engaged in an aggressive rehabilitation routine that got him medically cleared in less than five months. His shocking return is still talked about as one of those 'can't predict it' moments in Rumble history.
