Steelers running back Najee Harris rolled an ankle late in regulation during Sunday’s game against the Bengals. Concerns immediately emerged, given that Harris reportedly had a Lisfranc issue during training camp.

The Steelers, for now, are optimistic. Per a source with knowledge of the situation, Harris rolled an ankle, causing the injury that technically has been described as an issue with his foot. The Steelers are still trying to confirm the exact extent of the problem.
