He'll man up and carry on, he's Superman when it comes to these things.
For all the unnecessary flak people give Cena, I have never seen someone more dedicated to the WWE. Dude showed up at the tapings the day after major surgery a few years ago,just to visit,in his wheelchair. I'll never understand the hate Cena gets from the Internet fans. Now anyone could get a classic out of HBK like Cena did in 07 (one hour RAW match anyone?) but the dude got a decent match out of Khali! I think Cena deserves every bit of his success.
