CINCINNATI — Terrance West rushed for 94 yards and a touchdown, and a swarming Browns defense allowed just 165 total yards, as Cleveland rolled to a 24-3 victory over the Cincinnati Bengals on Thursday night at Paul Brown Stadium.

Cleveland (6-3) moved into a first-place tie in the AFC North with the Pittsburgh Steelers, who play at the New York Jets on Sunday.

It was the first regular-season loss at home for Cincinnati (5-3-1) since 2012. And, the largest margin of victory in the series since 1987.

Cincinnati, which began the season 3-0, fell apart in prime-time on Thursday night, highlighted by the worst performance of the season for quarterback Andy Dalton, who went 10 of 33 for 86 yards and three interceptions.

Browns quarterback Brian Hoyer, meanwhile, improved to 9-3 as a starting QB, with an efficient outing, going 15 of 23 for 198 yards. Cleveland rushed for 170 yards.

Cleveland led 17-3 at halftime, but put the score out of reach with a 10-play, 63-yard drive capped by a 1-yard touchdown by West, giving them a three-touchdown lead.

That was more than enough cushion for Cleveland’s defense, which has allowed the second-fewest second-half points in the NFL. The Browns blanked the Bengals after halftime.

The Browns defense produced the game’s first big play when linebacker Craig Robertson intercepted a Dalton pass and returned it 15 yards to the Bengals’ 18.

That led to a 4-yard touchdown run by running back Ben Tate, putting Cleveland ahead 7-0.

Dalton was 5-for-16 for 38 yards and an interception in the first half.

It was a mistake-ridden first half for both teams, which combined for eight penalties for 83 yards and three turnovers.

Cleveland increased its lead early in the second quarter when running back Isaiah Crowell scored on a 2-yard run, making the score 14-3.
