WWE Champion John Cena did not work Friday night's WWE live event in Portland, Oregon. Brad Maddox came out to open the show and announced that due to injury, Cena would not be working.
This goes right along with what we've been told in that Cena's left elbow has become an issue. Cena is scheduled to undergo surgery on the elbow early next week following Sunday's WWE title match at SummerSlam. He was also held off last Sunday's WWE live event in Oakland, California for precautionary purposes.
