Browns rookie quarterback Cody Kessler was knocked out of the game in the second quarter with a concussion, and his team fell behind the Cincinnati Bengals 21-10 at halftime Sunday at Paul Brown Stadium.
Kessler suffered a concussion when he collided with defensive tackle Domata Peko as defensive end Carlos Dunlap tackled him with 7:27 left in the second quarter. Kessler completed a shovel pass to tight end Gary Barnidge for an 11-yard gain on the second-and-13 play from the Bengals' 16.
Rookie quarterback Kevin Hogan replaced Kessler, who's started the past five games and performed well.
