The cause of Chuck Blazer death, at the age of 72, is not yet clear, but in 2013 he told a court he had rectal cancer, diabetes and coronary artery disease.
Chuck Blazer was a former Fifa executive committee member, who was also the general secretary of Concacaf, was a central figure in the Fifa corruption scandal.
In 2013 court appearance, he admitted to accepting bribes over the 1998 and 2010 World Cup bids and, when that information was made public two years later, was handed a lifetime ban from all football-related activities by Fifa.
Chuck Blazer turned whistleblower to aid the US government in its investigations into corruption within football’s world governing body and played a crucial role in the downfall of its long-time president, Sepp Blatter, and in prompting promises of reform within the organization.
In a statement, Chuck Blazer lawyers Eric Corngold and Mary Mulligan said Blazer had been instrumental in the development of football in the region, and his misconduct “should not obscure Chuck’s positive impact on international soccer”.
The statement continued: “Chuck felt profound sorrow and regret for his action. He expressed sincere remorse towards his former constituents and colleagues, and to all of the soccer players disappointed by his conduct.”
