The Pittsburgh Steelers continue to suffer attrition on the defensive side of the ball. The inside linebacker position in particular has had trouble staying healthy. Cole Holcomb and Kwon Alexander were lost in back-to-back weeks. ILB Elandon Roberts stepped up in a big way and had been playing 100 percent of the Steelers’ defensive snaps. He was also acting as the defense’s quarterback, wearing the green communication dot to field play calls from the sideline. He was injured on Sunday against the Arizona Cardinals. He suffered a groin injury, attempted to come back, and immediately realized he couldn’t continue to play.
