While the Steelers have yet to add another running back to a depth chart that includes only tailbacks Fitzgerald Toussaint and Jordan Todman and fullback Will Johnson, the Steelers on Tuesday signed running back Abou Toure to the practice squad.
Toure, who played college football at Tennessee-Martin, was undrafted in 2015. He spent time with the Colts and Cardinals this year, appearing in three preseason games with the Colts.
The Steelers also have running back Rajion Neal on the practice squad.
Toure had a tryout on Tuesday with the Steelers, along with guard Lamar Mady and defensive end Brian Mihalik. Neither of the other two were signed, to the active roster or the practice squad.
