Johnson (toe) returned to practice Friday, Brian Batko of the Pittsburgh Post-Gazette reports.
Johnson is questionable for Saturday night's game against Las Vegas after managing one limited practice Tuesday ahead of back-to-back absences Wednesday and Thursday. Steelers RB Najee Harris revealed Friday afternoon that Johnson had rejoined the team for its end-of-week practice, which won't show up on the official injury/practice report. In any case, Johnson said he'll be fine to play and now seems to be moving in that direction.
