Trevor Pryce sacked Carson Palmer in the end zone for a safety, making it 26-10 with 6:52 left.
It was another disappointing loss for the Bengals, who lost to the Buffalo Bills on Sunday in game they led 31-14 but were outscored 35-0 in second half.
The anticipated matchups between Cincinnati’s dynamic receiving duo of Chad Ochocinco and Terrell Owens and New York’s shutdown cornerbacks Darrelle Revis and Antonio Cromartie finished decidedly in the Jets’ favor.
Ochocinco had four catches for 41 yards, while Owens finished with three receptions for 17 yards.
The Jets took advantage of Jim Leonhard’s interception, New York’s first in seven games — their longest drought since 1979 — early in the second quarter.
Keller had a 21-yard catch on first down from the Jets 34 and Bengals cornerback Jonathan Wade, signed earlier in the week, was called for a major face-mask penalty, adding 15 yards and putting the ball at Cincinnati’s 30. After three runs by LaDainian Tomlinson put the Jets at the 13, the drive stalled and New York settled for a 27-yard field goal with 9:01 left in the first half.
Cincinnati had another promising drive short-circuited when Palmer threw into triple coverage to Owens in the end zone and Cromartie picked it off.
