Trying to snap a two-game losing streak, the Seahawks flew to Lucas Oil Stadium for a Week 4 inter-conference duel with the Indianapolis Colts. Seattle would trail as Colts running back Donald Brown got a 1-yard touchdown run in the first quarter, followed by quarterback Peyton Manning's 5-yard touchdown pass to wide receiver Reggie Wayne. The Seahawks would get on the board with a 38-yard field goal from kicker Olindo Mare, but Indianapolis would close out the half with Manning's 21-yard touchdown pass to wide receiver Austin Collie. Following running back Joseph Addai's 12-yard touchdown run in the third quarter, the Colts would seal the win with kicker Adam Vinatieri's 37-yard and 19-yard field goals. Seattle would end the game with quarterback Matt Hasselbeck getting a 1-yard touchdown run and completing a 1-yard touchdown pass to fullback Owen Schmitt.
