Johnson failed to catch his lone target during Thursday's 24-21 loss to the Bengals.
Johnson appeared primed for an increased role Thursday after DJ Chark went down early with a broken ankle, but he ended up playing only nine offensive snaps while Tavon Austin stepped in as the No. 3 wide receiver after missing the first three games of the year. Even with Chark likely gone for the rest of the season, it doesn't appear expanded opportunities are on the immediate horizon for Johnson.
