Toussaint is expected to lead the Steelers' rushing attack Saturday against the Bengals, since teammate DeAngelo Williams (ankle) has been ruled out, ESPN.com reports.
Toussaint has rushed just 18 times for 42 yards this season, but the second-year tailback is slated to assume the bulk of Pittsburgh's backfield work Saturday in wake of Williams' untimely injury. While offensive coordinator Todd Haley said Toussaint will be "the guy", fellow running back Jordan Todman also figures to see some touches in this weekend's postseason tussle.
