"Few players in recent history have meant more to the Chiefs franchise and the Kansas City community than Derrick Johnson," Chiefs Chairman and CEO Clark Hunt said in a statement. "His tireless work ethic and passion for the game made him one of the most productive defensive players to ever wear a Chiefs uniform and one of the most respected players both in our locker room and around the league. 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."
