As mentioned before, John Cena will be leaving WWE for some time to film his upcoming American Grit TV series.
Wrestling Inc reports that his last scheduled appearance is on October 11th, which is the Smackdown after No Mercy.. It was previously reported that Cena would be off WWE TV for the entire year after No Mercy. However, that does not appear to be the case now. He is scheduled for Survivor Series, which takes place on November 20th and also has scheduled appearances in late December for WWE’s holiday events.
