According to a tweet by Steelers beat writer Joe Rutter, both Bell and Roethlisberger will miss this week's game versus the Cleveland Browns, according to Steelers' OT Marcus Gilbert.
With Antonio Brown already out, that means the Steelers will be without their No. 1 RB, No. 1 WR, and starting QB.
JuJu Smith-Schuster and Martavis Bryant will be the team's top WRs, with Roosevelt Nix and Stevan Ridley mixing in at RB, with Landry Jones taking over at QB.
