Coming off their shutout home win over the Rams, the Seahawks flew to Candlestick Park for a Week 2 NFC West showdown with the San Francisco 49ers. Seattle would trail early in the first quarter as 49ers kicker Joe Nedney got a 37-yard field goal, along with running back Frank Gore getting a 79-yard touchdown run. The Seahawks would respond in the second quarter as kicker Olindo Mare made a 36-yard field goal. San Francisco would reply with Nedney making a 42-yard field goal. As the Seahawks looked to bounced back from the deficit, quarterback Matt Hasselbeck received an injury as he was hit on the ground by 49ers linebacker Patrick Willis. Hasselbeck would leave the game with cracked ribs, yet Seattle closed out the half with backup Seneca Wallace completing a 1-yard touchdown pass to running back Julius Jones. In the third quarter, the Seahawks deficit quickly increased as on the 49ers' first offensive play of the second half, Gore would explode for an 80-yard touchdown run. San Francisco would close the game out in the fourth quarter as Nedney nailed a 39-yard field goal.
