Steelers Rashard Mendenhall has no timetable for return

Steelers RB Rashard Mendenhall admits that he has no timetable for a return from last January's torn ACL.  He went down just a week after Adrian Peterson but seems much further behind in the recovery process.  Mendy has been running but isn't participating at all in OTAs.  He's likely to start the season on the PUP list and may not contribute much at all in 2012.  Isaac Redman is the Steelers RB to own in fantasy this year.
