The Cowboys already have done more on their first drive Sunday against the Falcons than they did all of last week in a loss to the Broncos.
Dak Prescott threw a 13-yard touchdown pass to CeeDee Lamb, who was well covered by Fabian Moreau. The Cowboys have a 7-0 lead with 11:42 remaining in the first quarter.
Lamb has two catches for 50 yards.
Prescott, who struggled last week in his return from a right calf injury, completed 3 of 5 passes for 61 yards and the touchdown.
The Cowboys needed eight plays to go 73 yards.
