Major League Soccer and Falcons owner Arthur Blank are planning a "major announcement" Wednesday on a proposed expansion team to play in Atlanta's new downtown stadium.

Blank has long coveted a top-level soccer team for the city, and negotiations with the MLS intensified after he reached a deal on building a new $1 billion retractable roof stadium next to the Georgia Dome. Site preparation has already started, and the facility is expected to open in 2017.

Both the MLS and a top official from Blank's organization acknowledged last week that the two sides were close to a deal. The Atlanta Journal-Constitution reported that the new team would be announced Wednesday.

Blank, MLS Commissioner Don Garber and Atlanta Mayor Kasim Reed are scheduled to attend the news conference.
