Coming off their overseas trip to London and subsequent bye week, the Broncos donned their alternate orange jerseys and returned home for an AFC West duel against the Kansas City Chiefs, hoping to snap a 4-game losing streak. In the first quarter, quarterback Kyle Orton, playing on his 28th birthday, threw three touchdown passes: a 17-yarder to running back Knowshon Moreno, a 6-yarder to wide receiver Brandon Lloyd and a 40-yarder to wide receiver Jabar Gaffney. In the second quarter, quarterback Tim Tebow ran for a 1-yard touchdown, followed by linebacker Jason Hunter returning a fumble 75 yards for a touchdown, giving the Broncos a commanding 35-0 lead before the two-minute warning. The Chiefs got on the board, with a 5-yard touchdown run from running back Jamaal Charles, followed by a 40-yard field goal by placekicker Ryan Succop just before halftime. In the third quarter, Tim Tebow threw his first touchdown pass&#8212;a 3-yarder to fullback Spencer Larsen, but the Chiefs responded, with quarterback Matt Cassel throwing a 15-yard touchdown pass to wide receiver Dwayne Bowe. In the fourth quarter, Orton threw his fourth touchdown pass of the game&#8212;a 15-yarder to Lloyd. The Chiefs responded, with Cassel throwing a pair of touchdown passes&#8212;an 11-yarder to wide receiver Chris Chambers, followed by a 22-yarder to Bowe (both with failed two-point conversion attempts), but the outcome had already been decided in the Broncos' favor.
