Mike Nugent kicked a game-winning 42-yard field goal in overtime Sunday afternoon, giving the Bengals a 27-24 come-from-behind win over the Seattle Seahawks at frenzied Paul Brown Stadium.
Nugent's boot with 3:36 left in overtime hit the left upright and deflected through.
The Bengals are 5-0.
Quarterback Andy Dalton led Cincinnati back from a 17-point fourth-quarter deficit, and helped keep the Bengals unbeaten with their second-biggest comeback in franchise history.
The last time the Bengals won after trailing by 17 points in the fourth quarter was in 2004 at Baltimore.
Trailing 24-7 against the Seahawks at the beginning of the fourth quarter, Dalton took over. He threw for a touchdown, ran for another score, and led the Bengals on a 69-yard scoring drive without benefit of a timeout.
Nugent had a pair of big boots. His 31-yard field goal on the final play of regulation tied it at 24.
Nugent was good again from 42 yards in overtime, the ball bouncing off the left upright and still making its way inside the posts.
The stunning come-from-behind win matched the second-biggest comeback in Bengals history when they trailed in the fourth quarter.
Cincinnati is 5-0 for the first time since 1988. That was the last year that they went to the Super Bowl.
Dalton finished 30-of-44 passing for 331 yards and two touchdowns in yet another brilliant performance.
Tight end Tyler Eifert was his top target. He caught both TD passes and had eight catches for 90 yards. Running back Giovani Bernard rushed 15 times for 80 yards.
The Bengals' defense forced Seattle (2-3) to punt twice in overtime, giving them a chance to pull it out.
Seattle wasted a 169-yard rushing effort by running back Thomas Rawls, the injury replacement for Marshawn Lynch (hamstring). Rawls scored a touchdown on one of his 23 carries.
Carlos Dunlap had 1.5 of the Bengals' four sacks. Vincent Rey led Cincinnati with 14 tackles. Adam Jones had an interception.
