Towards the end of 2007, Cena suffered a serious injury at the hands of Mr Kennedy. That was Kennedy's days with WWE numbered. Cena had torn his pectoral and looked to be out of action for seven months. It looked more than likely he'd be missing the next year's WrestleMania. But to the shock of every wrestling fan, at the 2008 Royal Rumble, the number 30 number buzzed and out came John Cena. The pop was massive, mainly because it was so unbelievable to see him. How had he recovered from that injury so quickly? It was at this point that he started getting a reputation for having "mutant" recovery powers.
