The long-rumored Copa América Centenario tournament in the United States looks like it's about to become a reality.

CONCACAF announced on Monday that the confederation will hold a joint press conference with CONMEBOL on Thursday "to make a historic announcement" in Miami, the home base of CONCACAF.

Reports of the South American federation holding its biggest international tournament on US soil – which would include both the US and Mexican national teams – have been circulating since 2012, with various degrees of political wrangling supposedly holding up the process.

The website for beIN Sports reported earlier this month that an official announcement was indeed forthcoming on May 1. The special edition of the Copa América – to be held on the 100th anniversary of the South American confederation – will reportedly consist of 16 teams, including the US, Mexico, four other CONCACAF representatives and South America's 10 nations.

According to CONCACAF, attendees at Thursday's presser will include confederation president Jeffrey Webb, CONMEBOL president Eugenio Figueredo and "a number of internationally renowned" players from the past and present from both regions.

The Copa América is the oldest international continental soccer competition still in existence. It was first played in 1916 in Uruguay, who are the current champions after winning the 2011 edition vs. Paraguay and hold the record for most tournament wins with 15.
