The word making the rounds is Samoa Joe suffered a knee injury over the weekend at a house show against John Cena which lead him to miss Sunday’s house show. The online reports say Joe will be out of action for the next six weeks. The rumors before the injury occurred was that the plan was for Joe to face John Cena at No Mercy. Last night on Raw they announced that Cena would be taking on Roman Reigns at No Mercy. No official word from the WWE yet on the injury.
