The Steelers will be down to their third-string running back on Saturday in Cincinnati.

DeAngelo Williams will miss tomorrow’s game against the Bengals, Ian Rapoport of NFL Network reports. That leaves the Steelers, who already have Le’Veon Bell on injured reserve, down to Fitzgerald Toussaint and Jordan Todman at running back.

That means the Steelers have a big question mark at running back. Toussaint had 18 carries for 42 yards and Todman had four carries for 22 yards, and neither of them caught a pass. The Steelers just don’t know how Toussaint and Todman will play as the primary running backs in the offense, because neither has done it yet.

The good news for the Steelers is that Williams’ foot/ankle injury appears to be healing well enough that he could play next week. If the Steelers win tomorrow at Cincinnati, they’ll play next on Sunday, January 17 at Denver.

But getting to Denver will be harder with Williams on the sideline.
