The Cincinnati Bengals might want to hold off making any Super Bowl plans.

Byron Leftwich threw two touchdowns, Fred Taylor ran for a season-high 132 yards and the host Jacksonville Jaguars handed the visiting Bengals their first loss of the season, 23-20, Sunday night.

Cincinnati started 4-0 for the first time since 1988 -- the franchise's last Super Bowl season -- and entered the game as one of the last two undefeated teams in the league. But the Jaguars took advantage of good field position early and had two big stops late.

Josh Scobee kicked three field goals, including a 51-yarder in the second period and a 53-yarder with 9 minutes 45 seconds to play that gave the Jaguars (3-2) a 10-point lead.

Jacksonville's defense made two huge stops that kept Carson Palmer from engineering a fourth-quarter comeback.

Bobby McCray knocked the ball out of Palmer's hand at the Jacksonville 45-yard line with 1:28 to play. Akin Ayodele, who dropped a possible interception the play before, recovered it.

Cincinnati Bengals punter Kyle Larson is unable to get the ball off as Jacksonville's Nick Sorensen (41) and Derrick Wimbush rush in for the block.
