FALCONS 27, SAINTS 25:

In New Orleans, Matt Ryan hit Cordarrelle Patterson for a 64-yard gain with a minute to go, setting up Younghoe Koo’s 29-yard field goal as time expired to win it for Atlanta.

Ryan passed for 343 yards, connected twice with Olamide Zaccheaus for touchdowns, and the veteran quarterback also ran for a score on a bootleg.

Ryan’s second scoring pass gave the Falcons a 24-6 lead with 10:39 left in the fourth quarter. But the Saints rallied to briefly take the lead on Trevor Siemian’s 8-yard pass to Kenny Stills with 1:01 left.

New Orleans then missed a 2-point conversion try for the second time in the game, leaving the door open for the Falcons to win with a field goal.

Ryan needed just one play to burn the Saints’ defense for his fourth completion of more than 30 yards in the game — and his second long connection with Patterson. The versatile running back beat rookie Paulson Adebo down the right sideline to give him six catches for 126 yards on the day.

Even with top Falcons receiver Calvin Ridley unavailable while addressing mental health issues, Ryan completed 23 of 30 passes without a turnover.

Saints coach Sean Payton started Siemian on the heels of Jameis Winston’s season-ending knee injury a week ago, and intermittently mixed in Taysom Hill behind center. Siemian passed for 249 yards and two touchdowns without an interception, and Hill completed both of his passes for 33 yards. But both quarterbacks were hindered by a combination of penalties, dropped passes and protection breakdowns.
