In the second quarter, Minnesota sealed the win early as QB Tarvaris Jackson completed a 19-yard TD pass to WR Robert Ferguson, Longwell nailing a 46-yard field goal, and RB Chester Taylor getting an 84-yard TD run. In the third quarter, San Francisco would get their only score of the game as QB Shaun Hill completed a 5-yard TD pass to WR Arnaz Battle. With the loss, the 49ers fell to 3-10.
