Toussaint had one reception for three yards against Indianapolis on Saturday before exiting with a left leg injury.
Knile Davis got the start, with Toussaint having to wait until Pittsburgh's fourth offensive possession before seeing his only touch of the game. Le'Veon Bell (groin) and rookie James Conner are 1-2 respectively on the depth chart, with Toussaint, Davis, Terrell Watson and Trey Williams all competing for roster spots. If Toussaint is cleared, each running back should have one final opportunity to impress head coach Mike Tomlin in the final preseason game Thursday against Carolina.
