Najee Harris questionable for wild-card bout vs. Chiefs
Harris was a full participant at practice Friday after missing Thursday's session.
The first-round rookie put on a show this season, ranking fourth among all players with 1,667 scrimmage yards. The Alabama product also had an NFL-high 381 touches to go along with 10 total touchdowns.
Harris is the Steelers' only active player with an injury designation for Sunday.
On Thursday, Pittsburgh opened its 21-day window to remove JuJu Smith-Schuster from injured reserve, but the wide receiver has yet to be activated.
