Trying to break a two-game losing streak, the Broncos went home for a Sunday Night fight with the Seattle Seahawks.  This game would be notable for the NFL debut of QB Jay Cutler.  In the first quarter, the Broncos struck first with kicker Jason Elam's 37-yard field goal for the only score of the period.  In the second quarter, Denver's lead increased with Cutler's 7-yard TD pass to TE Stephen Alexander.  However, the Seahawks got into game with DE Darryl Tapp's 25-yard interception return for a touchdown.  After a scoreless third quarter, Seattle took control of the game with RB Shaun Alexander's 1-yard TD run, along with kicker Josh Brown's 44-yard and 23-yard field goal.  The Broncos responded with a huge play, as Cutler completed a 71-yard TD pass to WR Brandon Marshall.  However, Denver's defense couldn't hold off the Seahawks' response, as Brown nailed a 50-yard field goal, spoiling Cutler's debut.  With their third-straight loss, the Broncos fell to 7-5.
