The Steelers could be without one of their most explosive weapons in Week 11, as Jaylen Warren popped up on the injury report with a back injury.

Warren entered Thursday with no injury designation, but now it could be a game-time decision.

Fellow running back Najee Harris, who missed Wednesday’s practice with an ankle concern, returned to full participation Thursday.

Warren has 55 carries for 217 yards (3.9 avg) and five rushing touchdowns.
