The Seahawks travelled to Monster Park to face division rival San Francisco. Buoyed by the return of Shaun Alexander to the starting line-up, and having Matt Hasselbeck dressed as the 3rd quarterback, the Seahawks expected to take a stranglehold on the NFC West. Instead, they played a flat first half and fell behind by 20 points - 13 of those coming after 3 turnovers. The Seahawks also allowed the 49ers to gain 163 rushing yards in the first half, whereas Alexander had only 9 yards on 7 carries. He would finish with 37 yards on 17 carries. A different Hawks team appeared in the second half, scoring quickly on a 38-yard touchdown reception by Deion Branch. The Seahawks added another long touchdown reception by Darrell Jackson with 6:40 remaining in the game, but could not get any closer. A key sequence in the last 2 minutes of the game saw Alexander stopped for a loss on 4th and 1. Following the change of possession, 49ers RB Frank Gore fumbled, recovered by Grant Wistrom. Given a second life, the Seahawks allowed a 9-yard loss on a sack before Seneca Wallace threw an interception. Instead of owning a 3-game lead in the division, the Seahawks only lead the surprising 49ers by a game. The teams meet again December 14 at Qwest Field..
