The group stage of the Davis Cup Finals has been scrapped in favour of a return to home or away ties.
The Finals have undergone numerous changes since the World Group was disbanded at the end of 2018.
The latest alteration will ensure teams play fewer ties on neutral venues, and also reduce the workload on the players.
International Tennis Federation president David Haggerty said: "Moving the Davis Cup September stage from six-day group stage events to two-day home or away ties will ease players’ schedules immediately following the US Open, while maintaining the intensity of the competition that they all love.
