Caribbean Football Union (CFU) president Gordon Derrick has been banned from all football-related activities for six years by FIFA's ethics committee.
Derrick, who is also the general secretary of the Antigua and Barbuda Football Association, was found guilty of a series of bribery and conflict of interest charges.
A director of the Antigua Commercial Bank, Derrick replaced Jack Warner as CFU boss in 2012 and was favourite to follow Warner's path to the presidency of CONCACAF.
Last year, however, the Antiguan was barred from standing in the CONCACAF regional presidential election, success in which would have made him a FIFA vice-president.
FIFA has claimed that the case against Derrick focused on "alleged conflicts of interest, offering and accepting gifts and other benefits, mismanagement of funds, abuse of position and disloyalty".
Derrick was also ordered to pay a fine totaling 30,000 Swiss francs (£23,000).
