Later in the 3rd, the Vikings scored a TD paired with a failed 2-point conversion attempt. The Packers responded with a 57-yard run by Ryan Grant to the Minnesota 2 that set up a 1-yard touchdown rush by Aaron Rodgers to make the score 24-12. The Vikings Adrian Peterson scored a 3-yard rushing touchdown on their next drive to bring the Packers lead back to 5 points with 2:43 left in the 4th quarter. The following Vikings onside kick was knocked out of bounds after touching safety Atari Bigby. The Packers then went three and out and punted the ball back to the Vikings with 2&#160;minutes left.
