It was announced this week on Monday Night Raw that John Cena would be defending the United States Championship at the Hell in a Cell pay-per-view this Sunday night. There's no word yet on who he would be defending the title against. My guess would be Dolph Ziggler. That will be Cena's last show before he takes time off. Cena will be off WWE programming until late December.
Here is the updated card for Sunday's Hell in a Cell pay-per-view:
Hell in a Cell match
The Undertaker vs. Brock Lesnar
Seth Rollins (champion) vs. Kane
