Johnson (knee) is expected to play Thursday against the Seahawks, Jeremy Fowler of ESPN.com reports.
Johnson missed the final three games of last season due to a knee injury and then sat out the Cardinals' Week 3 loss at San Francisco with a knee issue. After being listed as limited on all three Week 4 practice reports, he's slated to be back in action Thursday and likely will retake the starting left tackle job from Kelvin Beachum.
