The Steelers have lost long snapper Greg Warren for the rest of the year.  He played in all 14 games (0 starts) for the Steelers this season.  He has now played in 69 games (0 starts) in his five years with the Steelers.  The Steelers have signed Jared Retkofsky to replace Warren as the long snapper and he has played for them before.  He should do a decent job for them the rest of the way.
