Alfredo Hawit, the former interim President of the Confederation of North, Central America and Caribbean Association Football (CONCACAF), has pleaded guilty to four conspiracy charges at a court in New York City.
The Honduran, also a former vice-president of FIFA and the head of the National Autonomous Federation of Football of Honduras (FENAFUTH), agreed to be extradited to the United States in January after he was indicted in connection with the corruption scandal engulfing world football's governing body.
He was arrested in Zurich on the morning of FIFA’s Executive Committee meeting in December and initially resisted his extradition from Switzerland.
Now, he had admitted to a trio of charges which relate to marketing and television rights.
The 64-year-old was accused of taking millions of dollars in bribes to arrange the rights for companies in Florida and Argentina.
Each of the three charges could result in 20 years in jail, it has been reported, while he will also forfeit $950,000 (£664,000/€832,000).
Hawit refused to comment when leaving the court in Brooklyn, after being released on $1 million (£699,000/€875,000) bail.
He had previously plead not guilty to 12 corruption charges in January, when he also had a request to be placed into house arrest rejected.
The probe into corruption within FIFA in the United States has seen a total of 42 officials and entities indicted.
It is claimed that the money used in illegal deals was transferred through the US using the country's banks.
Hawit's plea follows the admission of his fellow countryman Rafael Callejas, who plead guilty to taking bribes in connection with the awarding of media and marketing rights for FIFA World Cup qualifying matches.
The 72-year-old, a former President of Honduras who was head of FENAFUTH for 13 years, has agreed to a plea deal and will forfeit $650,000 (£456,000/€580,000), news agency Reuters has reported.
Like Hawit, each count against him also carries a maximum penalty of 20 years in prison.
Both men were among 16 officials indicted by the American Department of Justice in December.
They have also been named by FIFA who are attempting to reclaim "tens of millions of dollars" from corrupt officials under its own roof.
The governing body submitted documents to US authorities after claiming that the cash had been "pocketed" illegally.
