Harris "up in the air" for Week 13

Steelers RB Najee Harris' status for Sunday's game vs. the Falcons is "up in the air," according to NFL Network's Ian Rapoport. Harris' abdominal injury is not major, Rapoport adds, so this shouldn't be a long-term absence. But Pittsburgh's backfield is in flux right now with both Harris and Jaylen Warren (hamstring) iffy for Week 13. If both guys miss, Benny Snell figures to operate as Pittsburgh's lead back, with Anthony McFarland in a change-of-pace role.
