Over the last 13 seasons, Derrick represented himself and the Chiefs organization with integrity and class, and he will always be a part of our Chiefs family.”

I love Kansas City and this fan base, they’ve always had my back. I’m grateful I had the opportunity to spend 13 years in a place I love.”
