The International Ice Hockey Federation says Chappot was first treated at a hospital two weeks ago. He returned home before his condition became worse on Apil 1 and he was admitted to an intensive care unit.
The IIHF says Chappot "was a legend in the French-speaking part of Switzerland and one of the best centers in the country in the '60s."
He was the Swiss league's leading scorer in the 1964 season. AP SSCSSC
