Kansas City, Mo. ? The Kansas City Chiefs on Thursday said team president Carl Peterson had agreed to a four-year contract extension, keeping him at the team’s administrative helm through the 2009 season.

The current contract for Peterson, who joined the club in December 1988, was scheduled to expire at the end of the 2005 season.

The Chiefs declined to release any information about Peterson’s new contract.

Team owner Lamar Hunt focused on the triumphs during Peterson’s 16 seasons as the Chiefs’ leading executive — eight playoff appearances, four AFC West titles and a trip to the AFC Championship in 1993. During the 17 years before Peterson, the team reached the playoffs once and had only four winning seasons.

“Carl was instrumental in leading the Chiefs back to the top echelon of the NFL,” Hunt said in a written statement.

Team officials also noted that the Chiefs had sold out 117 consecutive home games.
