Patriots rookie safety Pat Chung suffered a head injury in the third quarter and his return is questionable.
Chung appeared shaken up when combining with Brandon Meriweather to tackle tight end Dustin Keller on the Jets' first possession of the second half. Trainers forced him off the field after the play, but he later returned for the kickoff after the Jets scored on the drive.
As he came off following the kickoff, trainers again grabbed him and re-examined him. He remains on the sideline.
