The Pittsburgh Steelers will likely start the 2012-2013 season without two key offensive starters. Running back Rashard Mendenhall and nose tackle Casey Hampton both suffered torn ACLs at the tail end of last season, and Steelers General Manager Kevin Colbert told the Pittsburgh Tribune he doesn't expect either player to be ready for opening day.

“My guess is they’ll open the season on PUP (the physically unable to perform list),” Colbert said.

“You’ve got to remember both of those injuries happened late in the year.”
