Hoping to rebound from their disappointing home loss to the Patriots, the Vikings flew to Monster Park for a Week 9 clash with the San Francisco 49ers. In the first quarter, the Vikings would draw blood, as kicker Ryan Longwell completed a 21-yard field goal for the only score of the period. In the second quarter, the 49ers get two Joe Nedney field goals (a 25-yarder and a 30-yarder) and take the lead. After a scoreless third quarter, Nedney would put the game away for San Francisco as he nailed a 51-yard field goal. With yet another disappointing loss, the Vikes fell 4-4..
