Write an article that answers the following question: Which team was leading at halftime?
With Dallas posting a 21-12 halftime lead, Green Bay kept chipping away and Aaron Rodgers led the Packers on a late nine-play 75-yard scoring drive that culminated in a 12-yard touchdown pass to Davante Adams with 11 seconds remaining in the game. Damarious Randall earlier added a pick-six to the scoring with a 21-yard return of a Dak Prescott interception to give Green Bay a 28-24 lead at 9:56 of the fourth quarter. Dallas had answered that, regaining the lead on an 11-yard Dak Prescott touchdown run after a grueling 17-play, eight-minute 79-yard scoring drive which left 1:13 on the game clock for Green Bay to work with. Dallas dropped to 2-3 with the loss, heading into its bye week, while Green Bay improved to 4-1 moving forward with a visit against division rival Minnesota Vikings October 15.
