The Steelers elevated Johnson to their active roster ahead of Monday night's matchup against the Giants, Brooke Pryor of ESPN.com reports.
Johnson was also elevated for the Steelers' Week 7 win over the Jets but didn't see the field. He'll add depth to Pittsburgh's wide-receiver room, as rookie Roman Wilson (hamstring) was just placed on injured reserve Monday. Expect Johnson to serve as a depth piece in the Steelers' WR corps while potentially contributing on special teams in Week 8.
