WWE has a storyline "injury" update on John Cena over on dot com. The official website notes he will appear on tonight's Raw Supershow from Dayton, Ohio. Below is an excerpt:
"The most obvious injury was the laceration to his head, which caused a substantial amount of bleeding," said WWE locker room physician Dr. Chris Amann. "He also has suffered a shoulder injury. Initial testing in the training room leads me to believe there may be torn muscles, possibly a torn rotator cuff or a biceps muscle."
