Coming off of their bye week with hopes to turn their season around, the Bengals flew to Arrowhead Stadium for a Week 6 duel with the Kansas City Chiefs.  In the first quarter, Cincinnati trailed early as Chiefs kicker Dave Rayner kicked a 32-yard field goal.  The Bengals would respond with QB Carson Palmer completing a 42-yard TD pass to WR T. J. Houshmandzadeh.  However, Kansas City would respond with QB Damon Huard completing a 3-yard TD pass to TE Tony Gonzalez.  In the second quarter, Cincinnati continued to struggle as Chiefs RB Larry Johnson got an 8-yard TD run, along with Rayner ending the half with a 20-yard field goal. After a scoreless third quarter, the Bengals would try to make a comeback in the fourth quarter as kicker Shayne Graham got a 33-yard field goal.  After Kansas City increased its lead with Huard and Gonzalez hooking up with each other again on a 26-yard TD pass, Cincinnati got within striking distance as Palmer and Houshmandzadeh hooked up with each other again on a 30-yard TD pass, along with Graham's 36-yard field goal.  Unfortunately, the Chiefs would hold on to get the win. With their fourth-straight loss, the Bengals fell to 1-4.  It also marked the first time in the Marvin Lewis era that Cincinnati had lost four-straight games.
