Pittsburgh Steelers' Smith-Schuster ruled out with rib injury

PITTSBURGH -- Trailing 24-7, the Pittsburgh Steelers won't have one of their top offensive threats if they attempt to mount a late-game comeback against the Cincinnati Bengals.

Wide receiver JuJu Smith-Schuster was ruled out with a rib injury late in the third quarter. When the injury occurred wasn't immediately obvious.

Smith-Schuster had three catches on four targets for 25 yards, including one that went for 16 yards. The Steelers already entered Sunday's game without their top target, as wide receiver Diontae Johnson was inactive with a knee injury sustained on the final play of the Week 2 loss to the Las Vegas Raiders.

Soon after, right tackle Chukwuma Okorafor was helped off the field after a false start after sustaining an apparent injury and was replaced with Joe Haeg. Okorafor was later ruled out and was being evaluated for a concussion.
