Coming off of their bye week, the Seahawks flew to Cleveland Browns Stadium for a Week 9 interconference duel with the Cleveland Browns.  In the first quarter, Seattle took flight as QB Matt Hasselbeck completed a 5-yard TD pass to WR Bobby Engram for the only score of the period.  In the second quarter, the Browns responded with RB Jamal Lewis getting a 2-yard TD run (with a failed PAT).  The Seahawks would reply with Hasselbeck completing a 6-yard TD pass to WR D. J. Hackett, along with WR/PR Nate Burleson returning a punt 94 yards for a touchdown.  Cleveland would end the half with kicker Phil Dawson getting a 19-yard field goal. In the third quarter, the Browns began to fight back with Lewis getting a 1-yard TD run.  Seattle's response came from kicker Josh Brown who managed to get a 39-yard field goal.  In the fourth quarter, Cleveland continued to fight hard as Lewis got another 2-yard TD run (followed by a failed 2-point conversion).  The Seahawks would then increase its lead with Brown kicking a 26-yard field goal.  However, the Browns finally took the lead as Lewis got another 1-yard TD run (followed by QB Derek Anderson's 2-point conversion pass to former Seahawk WR Joe Jurevicius).  Afterwards, Seattle would force overtime as Brown kicked a 22-yard field goal.  In overtime, the Seahawks got the ball to begin the period.  However, the drive stalled when Seattle couldn't convert on a 4th & 1.  Afterwards, Cleveland responded and ended the game with Dawson's game-winning 25-yard field goal.
