Arrington had not returned through the third quarter.
Gronkowski, who set an NFL record for a tight end with 17 touchdown receptions, left after he was taken down by Bernard Pollard at the end of a 23-yard gain with 24 seconds left in the third quarter. He limped off the field and walked to the locker room, but returned for the end of the Patriots' touchdown drive.
Arrington tied for the NFL lead this season with seven interceptions. The New England defense has struggled this year, ranking 31st in passing defense and 31st overall in yards allowed in the 32-team NFL.
