Pats C Koppen suffers left arm injury

FOXBOROUGH, Mass. -- Just what the New England Patriots needed: another injured Pro Bowler.

Center Dan Koppen has left the field after suffering an apparent left elbow injury late in the second quarter. His status is uncertain, but we will update.

Russ Hochstein entered the game as Koppen's replacement and will have the unenviable task of facing New York Jets nose tackle Kris Jenkins.

On Hochstein's first snap, although it wasn't his fault, Jets defensive end C.J. Mosley sacked Patriots quarterback Matt Cassel on a fourth-and-3 play from the Jets' 23-yard line.
