Preseason
The Chiefs conducted training camp at the University of Wisconsin–River Falls for the 19th and final consecutive year. The team will move training camp to St. Joseph, Missouri in 2010. They lost all four games in the preseason to the Houston Texans, Minnesota Vikings, Seattle Seahawks, and St. Louis Rams (for the Missouri Governor's Cup). In the Chiefs' game against the Seahawks, QB Matt Cassel suffered a sprained Medial collateral ligament (MCL), leaving his status as starting quarterback for opening day in doubt. The offense for the Chiefs struggled in all four games, scoring only 42 points in four games and the offensive line suffered numerous breakdowns which led to Cassel's injury. The offensive struggles led to offensive coordinator Chan Gailey's firing and head coach Todd Haley assuming playcalling duties.
