The surging Seahawks under former Jets coach Pete Carroll limited the Jets to 185 total yards of offense and forced two fumbles.  Golden Tate caught a touchdown from Russell Wilson then took a reverse and threw to Sidney Rice for a fourth-quarter score.  The Jets only score came when Wilson was strip-sacked and Muhammad Wilkerson ran in a 21-yard touchdown. It was the Jets' second straight loss to the Seahawks, and they fell to 3-6 and 0-2 against the NFC West.
