john cena is a very ferice fighter in the WWE but how much more can he take? i am only saying this dew to what happend at summer slam when john had to go through sergery it made me wonder i like john but you gotta wonder how much more can a man take? on one hand batista (the man responsible for john going into sergery) is a very strong fighter and even then he barely beat john and before the sergery the tissue litterally explodad so says the docter the docter also said this is a very painful thing to happen to your shoulder and john still stood tall for all we know that could have blown well he was out in the ring! And i read that 2 hours just 2 hours after sergery and john was back at WWE saying hello to everybody it seems to me that john will last many more years in the WWE but my guess is he will one day or another get an ingery so bad he will be out of the WWE at least for a while i hope my prediction is wrong but someone has to think of these things! what do you think?
