The Commanders capped their first offensive possession on Sunday with a touchdown.
Heinicke was 4-of-4 for 63 yards on the drive, including two connections with wide receiver Terry McLaurin for 32 yards.
The Falcons opened the game with a good drive of their own. Marcus Mariota ran for one first down and the Falcons picked up two others before things stalled out in Washington territory. Younghoe Koo‘s 48-yard field goal staked them to a short-lived lead on the road.
