Johnson didn't practice Wednesday due to a thumb injury, Teresa Varley of the Steelers' official site reports.
Johnson played 53 snaps on offense and caught one of his four targets for 17 yards in Sunday's 23-19 win over the Packers, but he may have emerged from the game with the thumb injury. With an absence from practice to begin Week 11 prep, Johnson's status is worth monitoring ahead of Sunday's game against the Browns. If the wideout ends up out this weekend, Calvin Austin and Allen Robinson could step into expanded roles alongside George Pickens.
