Schottenheimer passed away Monday in Charlotte, North Carolina, per ESPN’s Chris Mortensen.

Schottenheimer was diagnosed with Alzeimer’s disease back in 2014. He had been in hospice care since Jan. 30 due to complications from the disease, according to a statement from his family.

During a long coaching career that spanned three decades, Schottenheimer coached the Cleveland Browns, Kansas City Chiefs, Washington Football Team and the Chargers.

Over his 21 years as a head coach, he amassed 200 wins, seventh all-time in NFL history.

“So sorry to hear about the passing of Marty Schottenheimer,” former Indianapolis Colts head coach Tony Dungy tweeted. “He was a great man and a great coach. He impacted so many lives for the better, including mine. My heart goes out to the Schottenheimer family.”

Chargers owner Dean Spanos released a statement which read in part: “Marty was a tremendous leader of men and a man of great principle — the love and admiration his former players have for him to this day speaks volumes. You couldn’t outwork him. You couldn’t out prepare him. And you certainly always knew exactly where you stood with him. I am grateful that he was our head coach for five seasons, and I am even more fortunate to have been able to call him a friend.”
