Wrap-up: Bengals 23, Bills 20

Thoughts on the Cincinnati Bengals' 23-20 win over the Buffalo Bills:

What it means: The up-and-down season for the Bengals is on the rise again after beating the previously unbeaten Bills. The Bengals moved into a tie with the Steelers and Browns, who are all 2-2 this season. Cincinnati is young but it has been in every game this season.

Delivering the upset: Mike Nugent's 43-yard field goal finished off the comeback as time expired. The Bengals trailed by 14 points at halftime.

Thumbs up: Bengals defense. Cincinnati proved its No. 3 overall ranking on defense isn't a fluke. The Bengals limited the Bills to 13 offensive points (one touchdown was the result of an interception return) and 273 yards. Buffalo entered the game with the NFL's highest-scoring offense (37.7 points) that averaged 431 yards per game.

Quick rebound: After throwing two interceptions in the final 3 1/2 minutes of the first half (both of which were converted into touchdowns), rookie quarterback Andy Dalton was impressive in how be bounced back in the second half, when he completed 11 of 16 passes for 182 yards. On the game-winning drive, he connected on 3 of 4 passes for 46 yards and converted a third down by scrambling.

What's next: The Bengals head to Jacksonville to play the Jaguars.
