LATROBE — A day after moving atop Pittsburgh’s depth chart at running back, Steelers rookie Le’Veon Bell’s status is in doubt for Monday night’s preseason game against the Washington Redskins.

Bell aggravated a left knee injury during a training camp practice Thursday. Pittsburgh’s second-round pick out of Michigan State was on the ground for several minutes while being attended by trainers after going down in a pile among multiple defensive players.

Bell was eventually helped off the field and watched the final hour of practice with his knee heavily wrapped. He was not available to the media.

Steelers coach Mike Tomlin interrupted a question about whether it was a concern that Bell’s knee was repeatedly causing problems with a terse, “No.”
