Browns RB Nick Chubb sustained a knee injury at the 14:14 mark of the second quarter Monday in Pittsburgh.
Chubb, who was on his way to having a fantastic game rushing for 64 yards on 10 carries, was carted off the field and immediately ruled out for the rest of the game.
As he was being taken off the field, the crowd at Acrisure Stadium rose to give him a standing ovation.
