There is concern that John Cena may have suffered a knee injury during a Raw house show in Wilkes Barre, PA. Cena apparently injured his knee taking the Wasteland finisher from Wade Barrett. They quickly went to a finish with Cena winning with some sort of submission when the planned finish was an Attitude Adjustment off the ropes.
Cena, who was having problems putting weight on his leg after the match told the audience that if he needed to "time off after tonight", he would, but he wasn't being carried out and then left under his own power, limping.

Oh god, this sucks terribly. Right after they start the angle with Punk and Nexus. Where you do think they could go from here if Cena really is out through Wrestlemania?
