Walter Payton, the legendary Chicago Bears running back known as “Sweetness,” died on November 1, 1999, from bile duct cancer (cholangiocarcinoma) that developed in the setting of a serious chronic liver disease called primary sclerosing cholangitis. He was 45–46 years old at the time and had publicly revealed his illness earlier that year, which led to a large outpouring of support from fans and the NFL community.

Quick Scoop: What Happened to Walter Payton?

  • Walter Payton announced in February 1999 that he had a rare liver disease called primary sclerosing cholangitis, which damages the bile ducts and liver over time.
  • This condition is strongly associated with an increased risk of bile duct cancer (cholangiocarcinoma), which is what ultimately caused his death.
  • He died on November 1, 1999, at his home near Chicago, after months of battling complications from his liver disease and cancer.
  • Following his death, the NFL and the Chicago Bears held tributes, and the team wore a special #34 patch to honor him.

A Bit of Background on His Illness

  • Primary sclerosing cholangitis (PSC) is a chronic disease where the bile ducts inside and outside the liver become inflamed and scarred, eventually leading to liver failure or cancer in some patients.
  • In Payton’s case, his doctor at the Mayo Clinic confirmed that while PSC was the underlying liver disease, the immediate cause of death was bile duct cancer.
  • He used his final year in the public eye to raise awareness about organ donation and serious liver disease, which became a notable part of his legacy beyond football.

Legacy After His Death

  • Payton is widely remembered as one of the greatest running backs in NFL history and a symbol of toughness and work ethic.
  • His name lives on through honors like the Walter Payton Man of the Year Award, which recognizes NFL players for excellence on and off the field, including community service.
