1 Santonio Holmes hurts the Ravens again. The wide receiver has scored a touchdown in six straight games against the Ravens, reaching the end zone a total of seven times.
2 The Ravens' pass protection struggles in Blitz-burgh. Tackles Michael Oher, Oniel Cousins and possibly Jared Gaither have to protect quarterback Joe Flacco from James Harrison and LaMarr Woodley.
3 The Steelers go deep on the Ravens' secondary. In seven wins this season, Roethlisberger has completed 34 passes of 20 yards or more. The Ravens likely will start backups at left cornerback (Carr) and free safety (Tom Zbikowski).
