Rashard Mendenhall dresses, but sits
Earlier Sunday, sources told ESPN's Josina Anderson that Mendenhall would miss the game, barring any unforeseen changes.
Dwyer saw time because the Steelers' usual third-down back, Mewelde Moore, was out with an ankle injury.
The Steelers won 38-17 behind Ben Roethlisberger's five touchdown passes.
