Fresh off their road win over the Jets, the Broncos went home, donned their alternate uniforms again, and played a Week 14 AFC West rematch with the Kansas City Chiefs.  Denver trailed early in the first quarter as Chiefs kicker Connor Barth made a 26-yard field goal, along with CB Maurice Leggett returning an interception 27 yards for a touchdown.  The Broncos would close out the period with rookie RB Peyton Hillis getting an 18-yard touchdown run.  Kansas City answered in the second quarter as QB Tyler Thigpen completed a 13-yard touchdown pass to TE Tony Gonzalez, but Denver did close out the half with QB Jay Cutler completing a 12-yard touchdown pass to WR Brandon Marshall. The Broncos would tie the game in the third quarter as kicker Matt Prater nailed a 33-yard field goal.  Afterwards, in the fourth quarter, Denver took the lead as Cutler hooked up with Marshall again on a 6-yard touchdown pass.  From there, the defense prevented any possible rally from the Chiefs.
