Hoping to rebound from their divisional home loss to the Cowboys, the Redskins flew to Qwest Field for a Week 12 duel with the Seattle Seahawks. In the first quarter, the Redskins trailed early as the Seahawks Olindo Mare kicked a 45-yard field goal. In the second quarter, Washington took the lead as RB Ladell Betts scored on a 1-yard TD run. Seattle would respond when QB Matt Hasselbeck connected with RB Maurice Morris on a 4-yard TD pass. In the third quarter, the Redskins took the lead on successive scores by Shaun Suisham (26-yard field goal) and a Jason Campbell 8-yard TD pass to WR Antwaan Randle El. In the fourth quarter, the Seahawks tied the game when Hasselbeck completed a 10-yard TD pass to TE John Carlson. Afterwards, Washington regained the lead as Suisham nailed a 22-yard field goal. Late in the game, a Ledell Betts fumble opened the door for a Seattle comeback. However, Matt Hasselbeck threw an interception to CB Shawn Springs on the first play of the series with less than 2 minutes remaining in the game. The Redskins ran out the clock, and sealed the win in Seattle. The game marked the return of Redskins head coach Jim Zorn and running back Shaun Alexander to their former team. Clinton Portis, who was questionable to play, led the running game with 143 yards. Washington ended a 2-game losing streak with the win.
