Pittsburgh Steelers running back Najee Harris is questionable for Sunday's matchup against the Kansas City Chiefs with an elbow injury, according to Brooke Pryor of ESPN.
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.
