Initial X-rays on McCaffrey's injured ankle came back negative, David Newton of ESPN.com reports.
Ian Rapoport of NFL Network reports that McCaffrey "rolled" his ankle and likely avoided a major injury, though the star running back missed the entire second half of Sunday's loss to the Dolphins (after briefly attempting a return in the second quarter). With Carolina on bye in Week 13, the early reports suggest McCaffrey at least has some shot at avoiding an absence.
