He was scheduled to return to the United States on Wednesday evening before he suffered cardiac arrest.
The former international football player and coach had lost his wife of 35 years, Kate, last year after a prolonged battle with cancer.
234today confirmed his death from a member of his family as well as one of his close associates.
“He was not ill at all, never showed any signs of illness, but we suspect he never got over the death of his wife,” a friend said.
He is survived by four children and his mother.
