Abdullah is slated for an examination of his left foot Tuesday with Dr. Robert Anderson in North Carolina, Josina Anderson of ESPN reports.
Abdullah experienced an early end to Sunday's loss to the Titans, after which he donned a walking boot on his left foot. Subsequent X-rays didn't reveal any broken bones, but Ian Rapoport of NFL Network reported Monday that Abdullah may be dealing with a sprained foot. Tuesday's evaluation will presumably pin down the exact nature of the injury and an accompanying recovery timetable. Until the preceding is known, the Lions' RB pecking order will be in flux.
