Steelers Defense Faces Challenge Without Injured Star Cam Heyward

Cam Heyward had groin surgery and will be out about 8 weeks after getting injured against the 49ers.
Heyward's absence leaves a major hole in the Steelers' defense before facing the Browns' strong run game.
The Steelers struggled against the run in Week 1, and now lose their top defensive lineman.
Multiple players will need to step up to try to fill Heyward's role on the defensive line.
The Steelers expect Heyward's injury absence to last until around midseason.
