MIAMI -- Starting right guard Dan Connolly has left Sunday's game against the Dolphins in the first quarter with a back injury.
Connolly played the first two series before being replaced by third-year player Nick McDonald.
Connolly is questionable to return to the game, according to the Patriots. He walked to the locker room with members of the athletic training and medical staff.
UPDATE: The Patriots announced in the fourth quarter that Connolly would not return.
