"My family and I are saddened by the news of Walt Corey's passing," Chiefs Chairman and CEO Clark Hunt said. "An original Dallas Texan who joined the club in 1960, Walt was part of the formative years of the franchise. After his seven-year playing career, he went on to spend an additional 12 years coaching for the Chiefs. He remained invested in the Kansas City community as an Ambassador once he left the sideline and will be remembered for his determination and humility. Our thoughts and prayers are with his family during this difficult time."
