Cam Heyward is expected to miss around eight weeks with a groin injury.
Now, ESPN’s Adam Schefter is reporting that Diontae Johnson will miss “a few weeks” because of the hamstring injury he suffered in the loss to San Francisco.
Johnson was injured in the second half of the 30-7 loss.
Before going down, Johnson had three catches for 48 yards.
The loss means the Steelers will be without two big names on both sides of the ball with a big matchup against the Cleveland Browns on Monday night.
