Only two weeks have passed since the Falcons last meeting with the Saints.
When Atlanta (3-8) returned from their bye and traveled to New Orleans (9-2), they completely dominated their NFC South rival, 26-9.
The Falcons then went on to beat the Panthers the following week and most recently fell to Tampa Bay Buccaneers 35-22 at home.
The Saints have won their last two games since losing to the Falcons in Week 10. New Orleans defeated Tampa and Carolina to improve to 3-1 in the division.
Here's a look at what's changed with the Saints since the last meeting:
Michael Thomas continuing to add to record-setting season
The Saints' star wideout is having his best season to date. He's also having the best year of any receiver in the NFL.
Thomas recently became the first player in NFL history to catch more than 100 passes through 11 games. Thomas has caught 104 passes for 1,242 yards and six touchdowns.
The last time the Falcons played the Saints they were without cornerback Desmond Trufant. With Trufant back in the lineup, he'll likely spend a significant amount of the game lined up against Thomas.
Trufant is playing at his best coming off a two-game streak with an interception.
The Falcons hope that trend continues.
Penalties have been a problem recently
The Saints have committed 86 penalties for 699 yards this season.
In the last three games, including the loss to the Falcons, the Saints have recorded 33 penalties for 289 yards.
The amount of penalties lately is something head coach Sean Payton is not pleased with.
Marshon Lattimore could make his return
The Saints' Pro Bowl cornerback suffered a hamstring injury in the first meeting with the Falcons. He's missed the last two games because of it and is likely to make his return this week.
Lattimore was listed as a limited participant on the Saints' estimated injury report that was released on Monday.
Lattimore has become one of the league's top cornerbacks since being drafted as the 11th overall pick in the 2017 NFL Draft
