The Chiefs began the season well on September 6 with an impressive performance and easily defeated the Oakland Raiders at Arrowhead 28-8. Kansas City sacked the Raiders quarterbacks 10 times, with Derrick Thomas collecting 6 by himself.
On September 13, Kansas City fell to the Jacksonville Jaguars on the road, 21-16.
On October 4, Kansas City conquered the Seattle Seahawks and the rain at Arrowhead, 17-6. Rich Gannon hit Andre Rison for an 80-yard touchdown pass after a 54-minute rain delay caused by a violent storm. The two teams combined for nine turnovers, five by Kansas City. The win improved the Chiefs' record to 4-1.
On November 16, against the Denver Broncos, the Chiefs defense was penalized five times on one drive, three of the penalties coming from legendary linebacker Derrick Thomas. The game is known now by Chiefs fans as the "Monday Night Meltdown". After that it was all downhill as the Chiefs suffered their first losing season since 1988.
