Cincinnati jumped out to an early lead with two touchdowns in the game's first five minutes, but the Giants came back, scoring on a 31-yard field goal by Lawrence Tynes just seconds before halftime to cut the lead to 17-6.
After scoring twice early on, Cincinnati added to its lead late in the second quarter, but was held to just a field goal by the New York defense. Mike Nugent's 28-yard kick made the Bengals' lead 17-3 with 4:22 left in the half.
The Giants come into Sunday's game 6-3 on the season, leading the NFC East by two games. Cincinnati is 3-5 this season, looking for their second home victory of the year. Despite their record, the Bengals have been solid when leading at half, with all three wins coming from halftime leads.
