Coach Mike Tomlin said Tuesday that Johnson (hamstring) is "probably unavailable" for Monday's game against the Browns, Brooke Pryor of ESPN.com reports.
This backs up a report from Adam Schefter of ESPN in which he relayed that the Steelers expect Johnson to miss multiple weeks due to the right hamstring injury he sustained in a season-opening loss to the 49ers. Tomlin also told Alan Saunders of PittsburghSportsNow.com that the team is awaiting the results of an MRI before honing in on an exact timeline for Johnson's return, but it appears he will be sidelined for at least Week 2. Assuming the veteran wideout is inactive this week, George Pickens, Allen Robinson and Calvin Austin all figure to have elevated target shares.
