ORCHARD PARK, N.Y. (AP) - Andy Dalton threw three touchdown passes to lead unbeaten Cincinnati to a 34-21 win over Buffalo. The Bengals sixth straight victory matches the team's best start to a season.
Dalton completed touchdown passes to Marvin Jones, Tyler Eifert and Jeremy Hill. Jones had nine receptions for 95 yards.
Dalton finished 22 of 33 for 243 yards for Cincinnati, which was also 6-0 to start the 1975 and '88 seasons.
The Bengals broke the game open by scoring 17 points on their first three second-half possessions to build a 34-14 lead.
The 3-3 Bills were undone by injuries and several penalties that allowed the Bengals to enjoy an average drive start of midfield in the first half.
