Context:  The Falcons traveled to New Orleans to take on their longtime rival Saints. They drew first blood as Mike Jonhson got a 1-yard touchdown pass from Matt Ryan to take a 7-0 lead. They then increased their lead to make the score 10-0 off of a Matt Bryant field goal from 37 yards out. The Saints got on the board as Chris Ivory ran for a 56-yard touchdown to make the score 10-7. In the 2nd quarter, the Saints took the lead as Drew Brees found Jimmy Graham for a 29-yard pass to make the score 14-10. Then the Falcons retook the lead as Tony Gonzalez caught a 6-yard pass from Matt Ryan to move ahead 17-14. The Saints moved back into the lead as Brees found Graham again on a 14-yard pass for a 21-17 halftime lead. After the break, the Saints went back to work as Brees found Marques Colston on a 7-yard pass to move ahead 28-17. The Falcons drew within 4 points with Gonzalez's 6-yard pass from Ryan to make the score 28-24 for the only score of the 3rd quarter and then Bryant kicked another field goal to make the score 20-yard field goal for a 28-27. However, the offense was then overpowered as the Saints scored their only points of the half off of Garrett Hartley's 31-yard field goal to make the final score 31-27. Tony Gonzalez became the first tight end in NFL history to have 100 receiving touchdowns.
