Alfredo Hawit, a top world soccer official until December, pleaded guilty on Monday to racketeering conspiracy, wire fraud conspiracy and conspiracy to obstruct justice.

Appearing in United States District Court for the Eastern District, in Brooklyn, Mr. Hawit, 64, admitted to having asked for and accepted hundreds of thousands of dollars in bribes from soccer marketing executives. He agreed to pay $950,000 to the United States. As the 17th of 42 defendants to be convicted in the Justice Department’s case, he could be sentenced to up to 20 years in prison for each count.

Mr. Hawit, a lawyer who previously led the Honduran soccer federation, had assumed a bigger role on the sport’s global stage after the United States announced a sweeping corruption case last spring focused on FIFA, soccer’s governing body.

He stepped in to lead Concacaf, one of FIFA’s six regional confederations, which oversees the sport in North America, Central America and the Caribbean, after its president, Jeffrey Webb, was indicted in May. Mr. Webb has since pleaded guilty.
