Trying to snap a two-game losing skid, the Broncos flew to Arrowhead Stadium for an AFC West duel with the Kansas City Chiefs.  In the first quarter, Denver drew first blood with kicker Jason Elam getting a 44-yard field goal.  The Chiefs would respond with kicker Dave Rayner getting a 38-yard field goal.  In the second quarter, the Broncos trailed as K.C. Safety Bernard Pollard blocked a punt that was deep in Denver territory.  The ball would roll out the back of the endzone for a safety.  The Broncos would respond with Elam kicking a 50-yard field goal.  However, the Chiefs would regain the lead prior to halftime as Rayner kicked a 36-yard field goal. In the third quarter, Denver retook the lead as rookie RB Selvin Young got a 20-yard TD run, along with LB Nate Webster returning a fumble 58 yards for a touchdown.  Kansas City would answer with Rayner nailing a 39-yard field goal.  Fortunately, in the fourth quarter, the Broncos closed out the game with QB Jay Cutler completing an 18-yard TD pass to TE Daniel Graham. With the win, not only did Denver improve to 4-5, but it also marked their first win at Arrowhead Stadium since 2002.
