Wrap-up: Dolphins 22, Bengals 14

A few thoughts on the Dolphins' 22-14 win against the Bengals:

What it means: The Dolphins remained undefeated through four road games and pulled within a game of -- at least -- second place despite more offensive problems. The New York Jets were shut out at home and slipped to 5-2. The New England Patriots played at 4:15 p.m.

Red-zone trend: The Dolphins got inside the Bengals' 25-yard line five times, but managed only one touchdown, a 1-yard Ricky Williams run in the fourth quarter.

Carpenter on fire: Miami's inability to score touchdowns meant another big day for kicker Dan Carpenter. For the second straight week, he converted five attempts to keep Miami in the game. He made a 54-yarder at the end of the first half to pull Miami within two points.

Clutch play: Sean Smith, who lost his starting right cornerback job to Jason Allen just before the season started, recorded his first NFL interception to kill a 15-play Bengals drive at the Dolphins' 7-yard line late in the fourth quarter.

Defensive containment: The Dolphins didn't record a sack or force a fumble. They had only one tackle for a loss. Their leading tackler was slot corner Benny Sapp. But they kept the Bengals in check. Bengals running back Cedric Benson averaged 3.5 yards a carry. Carson Palmer passed for only 156 yards and completed less than 50 percent of his passes.

What's next: The Dolphins will visit M&T Stadium to play the Baltimore Ravens, who will be coming off their bye.
