Johnson rushed once for eight yards and caught his lone target for nine yards during Sunday's 17-9 loss to the Chiefs.
The 27-year-old rushed for minus-four yards on his only offensive snap in the season opener, but he received two touches on six offensive snaps Sunday. No. 2 tailback Tank Bigsby saw more of the field but didn't touch the ball, as starter Travis Etienne was the only back to be a real factor. Johnson appears locked in as Jacksonville's tertiary option in the backfield.
