There was a planned injury angle scripted into this week's WWE Raw for John Cena. I'm told they wanted to make Cena appear vulnerable against Dolph Ziggler thus the angle was planned.
The kicker is Cena's spill to the outside. Some believe it was a shoot while others are telling us it was a work. Cena wrote on Twitter he was undergoing an MRI on Tuesday. From everything we've heard he is scheduled to undergo an MRI but we're still sorting through what's legitimate and what's not.
