Tight end Tyler Eifert caught three touchdown passes from Andy Dalton as the Cincinnati Bengals improved to 8-0 for the first time in franchise history with a 31-10 victory over the Cleveland Browns at Paul Brown Stadium.
In last year's Thursday night match-up against the Browns, Dalton had a career-worst performance, with a 2.0 rating in a 24-3 loss, but he delivered a steady performance this year, going 21 of 27 for 234 yards and three touchdowns.
"A little different from last year, huh?" said Dalton, who improved to 4-7 in his career in primetime games.
Coach Marvin Lewis warned his side they have achieved nothing, despite their perfect start.
"We don't get anything for that," he said. "We've had to grind through. We've just got to do what we've done so far, take it one week at a time."
Receiver Marvin Jones had five catches for 78 yards against a Browns secondary playing without cornerback Joe Haden and strong safety Donte Whitner, who are both injured.
Browns quarterback Johnny Manziel was unconvincing after starting in place of injured Josh McCown, passing for 168 yards and a touchdown.
He was sacked three times in the second half, during which the Browns (2-7) managed just 32 total yards.
"They came out and played a lot of cover two in the second half," said Manziel. "Things looked open a couple of times. But I could've gotten it down to a tight end or a running back. We had momentum going into the second half. We just didn't do enough."
Cincinnati capitalised on the worst rush defense in the league by gaining 152 yards on the ground, led by running back Gio Bernard's 72.
On Cleveland's first possession of the third quarter, Manziel looked to have gained 13 yards on third-and-12 from his own 10-yard line only for a Cincinnati challenge to overturn the spot and the Bengals then converted that decision into three points when a 28-yard field goal by Mike Nugent gave them a 17-10 lead.
The clinching touchdown came early in the fourth quarter when receiver Mohamed Sanu scored on a 25-yard reverse with Dalton among the lead blockers, making the score 24-10.
"That's my quarterback out there ready to block," said Sanu. "All I saw was green turf."
