After four months of doubt and speculation, all signs now point to U.S. Soccer withdrawing as host of the 2016 Copa América Centenario tournament over unresolved concerns about legal liability that emerged after several top soccer and marketing officials connected to the tournament were arrested in May.

The event — featuring stars from South America like Lionel Messi and Neymar — was supposed to be a showcase for the American soccer community as well as the United States men’s national team. However, U.S. Soccer officials will not attend a meeting in Mexico on Thursday to determine the fate of the troubled tournament, and multiple officials with knowledge of the organization’s position indicated that if the United States did not host the Copa América, then it was also probable that its national team would not participate.

One official said it was unlikely that there would be a definitive announcement about the tournament’s status after Thursday’s meeting but said the two most likely outcomes would be for the tournament to be staged in Mexico or for a modified tournament to be held in South America.

Officials from Conmebol, the South American soccer confederation, and Concacaf, the confederation that oversees soccer in North America, Central America and the Caribbean, are to meet in Mexico City to try to find a way to salvage the event, set for next June. Planning for the tournament has been delayed since May, when 14 top soccer and marketing officials were arrested as part of a wider investigation into corruption in the sport in which authorities charged that kickback schemes were linked to the Copa.
