Andy Murray is in line to play his first Davis Cup tie for two years after being named in the Great Britain team to face Croatia in the World Group play-off later this month.
The world number three and Wimbledon champion has promised that, providing he does not pick up an injury during the rest of his US Open campaign, he will be in Umag for the clash which begins on Friday September 13.
Dan Evans is in pole position for the second singles spot after reaching the third round in New York as a qualifier but James Ward has also been named in the four-man team.
Along with Britain's doubles players, the pair have been the key figures in Britain's rise from the depths of a Europe/Africa Zone Group II relegation play-off only three years ago.
Evans is inexperienced on clay and captain Leon Smith will watch on in practice before deciding who to pick, but it would be a brave decision to leave out the 23-year-old from Birmingham given his current form.
The fourth member of the team is doubles specialist Colin Fleming, but there is no place for his partner and last year's Wimbledon champion Jonny Marray.
It came as a second disappointment in a matter of hours for the Yorkshireman, who with Fleming was beaten by the Bryan brothers in the quarter-finals of the US Open on Monday night.
Smith has left the option open to bring in another doubles player after the US Open has finished.
