The Steelers are planning as though injured running back DeAngelo Williams will not play against the Bengals, but Pittsburgh has not officially ruled him out of Saturday's playoff game, a source confirmed to ESPN's Jeremy Fowler.
The Steelers began practice at their indoor facility Friday morning and are expected to update Williams' status after the brief workout.
NFL Network reported earlier Friday that the Steelers considered Williams out for their wild-card round game against the rival Bengals.
Williams missed his second straight practice Thursday with the foot injury that he suffered in last weekend's regular-season finale against Cleveland. He was seen wearing a walking boot, but he was walking without a limp at the Steelers' facility.
The Steelers announced earlier this week that Williams is considered day-to-day. Williams, 32, rushed for 907 yards and 11 touchdowns this season.
Steelers offensive coordinator Todd Haley said Thursday that running back Fitzgerald Toussaint will be "the guy" this week unless Williams can play. Haley also said that running back Jordan Todman will be heavily involved in the offense.
