Overview

• Derrick Harmon exited in the second quarter against the Panthers with a knee injury, was carted to the locker room, and was ruled out, per Steelers communications chief Burt Lauten.
• Broadcast shots showed the rookie visibly upset on the cart, heightening concern before he was later seen back on the bench in street clothes after walking out on his own, according to sideline reporter Missi Matthews.
• Head coach Mike Tomlin had no halftime update, and multiple outlets reported that the severity and timetable remain unknown pending further evaluation.
• Behind the Steel Curtain reported Tomlin later described the injury as a knee sprain that is still being assessed.
• Harmon, the No. 21 pick expected to start after a strong camp and a preseason sack, is a key piece of Pittsburgh’s defensive line rotation if healthy.
