David Beckham will be present for an announcement in Miami on Monday where his Major League Soccer franchise is expected to be revealed.
A press release from the league said "an important announcement on the future of soccer in Miami" would be made.
The former England captain will be joined at the event by MLS commissioner Don Garber.
The long-awaited launch is set to bring to a close years of planning for Beckham's ownership group after they struggled to find a location for a new stadium.
The 42-year-old exercised his option to purchase an MLS expansion team in 2014 after joining Los Angeles Galaxy in 2007.
The press conference will take place at Miami's Adrienne Arsht Center and members of Beckham's ownership group will also be present.
The announcement will take the number of teams in the league to 25, with Los Angeles FC and Nashville taking up 23rd and 24th places respectively.
The former Manchester United star promised to bring the world's top players to Miami in 2014, saying he would make a global football team "loved by millions of people".
