context: Hoping to increase their winning streak after a win against the Saints, the Falcons played inside their dome for an NFC duel against the San Francisco 49ers. In the first quarter the Falcons trailed early with QB Alex Smith making a 12-yard TD pass to TE Vernon Davis. The Falcons problems continued when Michael Koenen's punt was blocked and recovered in their own endzone by DB Taylor Mays, putting the 49ers up 14-0. Then the Falcons replied with QB Matt Ryan completing an 8-yard TD pass to WR Harry Douglas. Then the Falcons took the lead with three field goals from kicker Matt Bryant. He made a 37-yard field goal near the end of the 2nd quarter and a 31-yard field goad in the 3rd. Under two minutes to play with the Falcons trailing 14-13, Ryan threw an interception to the 49ers' Nate Clements who appeared to be headed to the end zone and clinch the win. However wide receiver Roddy White chased him down and stripped the football which was recovered by Atlanta's Harvey Dahl. Ryan then engineered a drive in the other direction and Bryant kicks a 43-yard field goal with two seconds left giving the Falcons another win.
