Johnson (knee) did not participate in Wednesday's walkthrough, Josh Weinfuss of ESPN.com reports.
Johnson has missed the Cardinals' last two games due to an ankle injury. He hasn't been able to practice since sustaining the injury, and he would be a long shot to play against the Bengals on Sunday unless he returns to practice by Friday. Josh Fryar should remain the starter at left tackle for as long as Johnson is sidelined.
