The Davis Cup will be transformed into a new one-week World Cup of Tennis tournament in a major overhaul set for 2019.

The International Tennis Federation announced Monday that it had unanimously endorsed a proposal to create an 18-nation tournament that will take place in November during the traditional week of the Davis Cup final.

The season-ending tournament would consist of a round-robin format followed by a quarterfinal knockout stage. Each match will consist of two singles and one doubles over best-of-three sets.

The ITF is working with investment group Kosmos in a partnership worth $3 billion over 25 years.

ITF President David Haggerty called the changes "a complete game-changer for the ITF and for tennis."

"Our vision is to create a major season-ending finale that will be a festival of tennis and entertainment, featuring the world’s greatest players representing their nations to decide the Davis Cup champions," Haggerty said in an ITF press release.
