As seen on Monday's WWE Raw, Randy Orton up against Riddle.

The two Superstars fought a very good match with lots of back and forth action, leading to Riddle picking up the surprise win after he reversed an RKO into a crucifix pin.

Wrestling Observer's Bryan Alvarez reported the following today on Orton:

"I don't know the extent of what happened but Randy Orton hurt his shoulder. He was fighting out of the corner and Riddle went to give him an Exploder. And Randy, of course, did not take an Exploder. He blocked it and then he pulled back to do this very dramatic punch and he punched him. And then from that point forward, he could no longer use his right arm. He started throwing forearms with the left arm which looked horrible... He couldn't use that arm and you could see him kind of messing with his shoulder"
