PITTSBURGH — The Pittsburgh Steelers offense is now monitoring another key injury as running back Najee Harris popped up on the practice report with a knee injury, forcing him to miss a day of preparation.

Harris was not on the team’s initial estimated practice report to start the week. The Steelers held a walk-through but did not have their starting running back on the field

. They’ll have just one more day of practice, where they’ll test all of their injured players before making decisions on their status for game day.
