"The Steelers will be without their top quarterback and wide receiver when they play the Baltimore Ravens on Sunday night, but they will have their top running back in the lineup.

Rashard Mendenhall, who has missed the past four games with an Achilles tendon injury, is expected to return and start against the Ravens.

However, wide receiver Antonio Brown did not practice all week and will miss his second game in a row with a high-ankle sprain. He will join quarterback Ben Roethlisberger on the sidelines.

Also, Pro Bowl safety Troy Polamalu will miss his sixth game in a row with a torn right calf muscle.
