– Andy Dalton's fingerprints were all over one of the Bengals' greatest comebacks.

Dalton led Cincinnati from a 17-point deficit to a legacy victory over the Seattle Seahawks on Sunday. Mike Nugent's 42-yard field goal in overtime bounced off the left upright, but went through for a 27-24 victory.

It matched the second-biggest comeback in team history and came against the two-time defending NFC champions — a signature moment for unbeaten Cincinnati.

"For us to come back against a really, really good team is huge," said Dalton, who completed 30 of 44 passes for 31 yards with two touchdowns and an interception.

Nobody came up bigger than him. Trailing 24-7 heading into the fourth quarter, Dalton threw for a touchdown, ran for another and led the Bengals (5-0) on a 69-yard drive with no timeouts to get Nugent's 31-yard field goal on the final play of regulation.

Dalton is going through a growth spurt in his fifth season, leading the NFL in fourth-quarter passer rating. He went 13-for-15 for 135 yards in the fourth quarter and overtime on Sunday.

"We imploded in the third quarter, but we righted ourselves and started putting one play on top of another and kept going," coach Marvin Lewis said.

Seattle (2-3) punted twice in overtime, giving the Bengals a chance to pull it out. Nugent's deflected kick ended it with 3:36 left in overtime, leaving Cincinnati 5-0 for the first time since 1988, the last time it went to the Super Bowl.

The 17-point collapse matched the biggest in Seattle history. The Seahawks wasted 169 yards and a touchdown from rookie running back Thomas Rawls, filling in for the injured Marshawn Lynch.

"The most frustrating part is we didn't finish," Seahawks receiver Doug Baldwin said. "We're known for that and we didn't do that today."
