Last meeting
Running back Warrick Dunn's two touchdowns led the visiting Falcons to a 21-19 victory on Sept. 12, 2004.
Key matchup:
Niners quarterback Alex Smith vs. Falcons cornerback DeAngelo Hall. Smith showed a lot of guts battling through the pain in his return to the 49ers' starting lineup last week. But he will likely find throwing against Hall -- one of the top cornerbacks in the league -- even more excruciating. Hall has a pair of interceptions, but Smith has thrown only one interception in 127 attempts this season.
