Rivers, along with 2004 draft classmate Eli Manning, has not missed a start in over a decade. He even fought through the pain of playing through the torn ACL he suffered in the 2007 divisional round against the Indianapolis Colts to play against the New England Patriots in the Championship round.
He hasn’t given us a reason to believe that he will ever get an injury that will cause him to miss a significant period of time. It is worth noting though that Rivers is 35, turning 36 this December. In the new NFL, where players like Tom Brady and a few other players seem to be making it in their 40’s, it stands to reckon that Rivers could play out the three remaining years he has on his contract, and potentially longer.
