Wallace completed 18-of-30 passes and was picked off once in his third straight start for the Browns (1-3), who had lost their first three games by a combined 12 points. Peyton Hillis carried the ball 27 times for 102 yards and a score, while Ben Watson caught six passes for 60 yards.
The Browns, who were mired in a 1-9 skid against divisional opponents, snapped the Bengals’ eight-game win streak versus the AFC North.
Carson Palmer threw for 371 yards and two scores on 25-of-36 efficiency for the Bengals (2-2), who had won their previous two contests. Terrell Owens was the primary receiver for Palmer on the day, catching 10 balls for 222 yards and a touchdown.
It was the second-highest single-game yardage total for Owens and the third 200-yard game of his career.
