A tough first-half against the Browns ended with the Steelers losing two of their top offensive weapons.

James Conner and JuJu Smith-Schuster each left with injuries in the first half against Cleveland.

Conner, who returned Thursday after missing two weeks with a shoulder injury, left at the start of the second quarter after apparently re-aggravating that injury.

Smith-Schuster was taken to the locker room after receiving a hit to the head by a defender. He was ruled out with a concussion.

The Steelers also lost cornerback Artie Burns to a knee injury and linebacker Olasunkanmi Adeniyi to a concussion in the opening half in Cleveland.
