In the report, which you can read here, he noted that CM Punk appeared to have been injured in his match tonight. After Punk and Daniel Bryan defeated Luke Harper and Erick Rowan, Punk stayed down with his head on the floor as the referee and Bryan checked on him. Punk ended up getting to his feet and seemed OK walking to the back, but he did leave the stage about two minutes before Bryan while Bryan was high fiving fans. F4WOnline reports that the Punk did get hurt, but is not expected to miss any ring time.
The reader also noted that John Cena appeared to tweak his ankle during his match with Alberto Del Rio, but F4WOnline added that it appears that the injury was simply the story of the match.
