please keep in mind I was away from sports entertainment from about 2002-2011, so missed a majority of cenas rise to the top. I know he suffered a major injury in 2007-2008 when he made the surprise entry at the rumble at MSG. but has he suffered any other "major" injuries? at his age and workload rate, cena is a major injury away from having his career ending. if he ever suffers a complete tear of his acl, mcl, or having a muscle tear completely away from a bone, his career as we know it is over. and I hate to see anyone get injured, but with his workload rate and as many appearances as he makes, this might not be too far down the line. and with VKMs inability to create his heir apparent as face of the company, if cena ever goes down, the wwe is fucked.
