KANSAS CITY, Mo. -- David Cook and his brother will sing the national anthem at the Chiefs home opener in September, Chiefs officials announced Tuesday.

Cook, a Blue Springs native who was named the winner of the "American Idol" TV competition this season, and his younger brother, Andrew, will perform the anthem at the Sept. 14 game against the Oakland Raiders at Arrowhead Stadium.

David Cook originally went to the "American Idol" auditions in Omaha, Neb., because his brother wanted to audition. David ended up auditioning for the show also and became the champion of the seventh season of the show.

"We are very excited to have David and Andrew perform the anthem for our first regular season game of the 2008 season," Chiefs President Carl Peterson said in a news release. "The citizens of Kansas City are proud to call David one of our own, and we are very happy for all of the well deserved success he has achieved. We know our fans will give both David and Andrew a very warm reception on September 14th."
