Johnson (illness) doesn't carry an injury designation ahead of Sunday's game against the Cardinals, Teresa Varley of the Steelers' official site reports.
After not practicing Thursday due to an illness, Johnson was a full participant a day later, which sets the stage for him to face the Cardinals in Week 13. In last Sunday's 16-10 win over the Bengals, Johnson caught four of his eight targets for 50 yards, marking his second consecutive outing with eight targets, a rate of volume that gives him a degree of fantasy utility this weekend while facing 2-10 Arizona.
