Paraguayan Napout, also a former FIFA vice-president, and Marin have both pleaded not guilty to charges and their trial is due to begin at the United States District Court in Brooklyn on November 6.

Assistant United States Attorney Evan Norris said last month, however, that this date could change if new charges are added or if any new defendants are added to the indictment.

It comes as defendants in the wide-ranging corruption case involving vast swathes of football officials and marketing executives are continuing plea talks with US prosecutors.

The US Department of Justice has also announced the sentencing dates for several of those implicated in the scandal, which rocked FIFA to its core, who have pleaded guilty to charges such as money laundering and racketeering.

Jeffrey Webb, the former Confederation of North, Central American and Caribbean Association Football President and former FIFA vice-president, is due to be sentenced on January 24.

Webb, who is from the Cayman Islands, had initially pledged to clean up the corruption within CONCACAF when he took over from Alfredo Hawit before he became embroiled in the scandal.

He pleaded guilty to one count of racketeering conspiracy, three counts of wire fraud conspiracy and three counts of money laundering conspiracy in November 2015.

Hawit's sentencing was initially scheduled for October 5 but has been pushed back to March by US District Court judge Pamela Chen.

No reason has been given for the decision to move the hearing for the ex-FIFA vice-president.

Rafael Callejas, who served as President of Honduras from 1990 to 1994, is set to learn his fate on December 15.

The first sentencing hearing is due to be held on October 18, where former Guatemalan Football Federation (FENAFUTG) President Brayan Jiminez will appear in front of Chen.

Hector Trujillo, himself a former judge and who was previously the secretary general of the FENAFUTG, is set to be sentenced the following week on October 25.

The criminal probe in the US has largely centered on illicit television and marketing deals.

The implicated officials are accused of taking millions of dollars of bribes from marketing firms in exchange for sponsorship and marketing deals for regional football tournaments and other matches.

The investigation into corruption within FIFA in the US has seen a total of 42 officials and entities indicted.

American authorities are involved as the money was allegedly channeled through the country using US banks.
