Ian Rapoport of NFL Network reported Lewis could be let go following the 2018 season because the Cincinnati Bengals hold a team option on his contract for 2019.
It was previously believed Lewis had signed a fully guaranteed two-year extension that likely would have kept him safe for next season.
The Bengals have lost five of their last six games after starting 4-1.
