Johnson (knee) didn't practice Wednesday.
After Johnson was injured on the final play of last week's loss to the Raiders, head coach Mike Tomlin said Tuesday that the wideout is "looking better, not to be confused with great," per Brooke Pryor of ESPN.com. Johnson's status thus appears shaky for Sunday's game against the Bengals, with Thursday and Friday representing his remaining two chances to return to the practice field. James Washington should step up as the No. 3 receiver if Johnson is ruled out this week, with the Steelers potentially using more multi-tight end looks as well.
