Trying to snap a six-game slide, the Chiefs went home for a Week 15 intraconference duel with the Tennessee Titans.  In the first quarter, Kansas City trailed early as Titans QB Vince Young completed a 16-yard TD pass to WR Roydell Williams for the only score of the period.  In the second quarter, the Chiefs tied the game with QB Brodie Croyle completed a 10-yard TD pass to WR Samie Parker.  Tennessee would respond with kicker Rob Bironas getting a 37-yard field goal, yet Kansas City regained the lead before halftime as Croyle completed a 9-yard TD pass to FB Kris Wilson. In the third quarter, the Titans crept close as Bironas kicked a 37-yard field goal, yet the Chiefs answered with kicker John Carney getting a 36-yard field goal.  However, Tennessee retook the lead with Young and Williams hooking up with each other again on a 41-yard TD pass.  In the fourth quarter, the Titans sealed the win as Bironas nailed a 40-yard and a 25-yard field goal. With the loss, not only did Kansas City fall to 4-10, but it also marked the first time since 1987 that the Chiefs dropped seven-straight games.
