Former Kansas City Chiefs head coach Marty Schottenheimer passed away at the age of 77 on Monday after a lengthy battle with Alzheimer’s.

Schottenheimer spent a decade at the helm of the Chiefs, coaching from 1989 through 1998. On Tuesday afternoon, Chiefs Chairman and CEO Clark Hunt released the following statement mourning the loss of one of the organization’s greatest and most accomplished coaches.

Current Chiefs head coach Andy Reid expressed his condolences to the Schottenheimer family and paid tribute to the former coach when speaking to the media during Super Bowl week after Schottenheimer had been moved to hospice care.

“My heart goes out to the Schottenheimer family,” Reid said. “Marty and I were close, and what a great person. He was great to me as a young football coach. Nobody did it better than he did.”
