Cena's out for 6-8 months. He will surrender the title and someone will take his place in this Sunday's title match.
While I hate to see anybody get hurt, the timing may be right for Cena to take some time off anyway. The guy has been overused and shoved down the fans throats for the better part of two years now. Maybe taking some time away from the ring will help his image. It always seems to work for HHH!
Also, I hope they put Kennedy in his spot in the title match. It wouldn't even matter to me who won, as long as it isn't Cena!
