Original - 11:33 AM: The Kansas City Chiefs have relieved head coach Todd Haley of his duties, according to a news release from the team’s official site.

“This was a difficult decision but one that we feel is best for the future of the Chiefs,” Chiefs chairman and CEO Clark Hunt said in a statement. “Although there have been bright spots at different points this season, we have not made meaningful progress and we felt that it was necessary to make a change. We appreciate Todd’s contributions during his time with the club, and we wish him well in the future.”

The Chiefs are a disappointing 5-8 this season after a promising 4-3 start. Kansas City lost their first three games of the season to Buffalo, Detroit, and San Diego, but rebounded to win their next four in a row. Since Week 8, however, the club has gone just 1-4 as they have battled injuries at the quarterback position.
