Andy Murray will lead the Great Britain team in their Davis Cup clash against Luxembourg at the Braehead Arena in Glasgow from 8-10 July.
Victory in the Europe/Africa Zone Group II tie would see GB reach a promotion play-off against Belarus or Hungary.
British number two James Ward, who won the decisive rubber in the victory over Tunisia in March, will join Murray in the singles.
Murray's brother Jamie partners fellow Scot Colin Fleming in the doubles.
That team is retained from the success over Tunisia despite Fleming reaching the third round at Wimbledon with regular partner Ross Hutchins.
Andy Murray, who has not played in Great Britain's last two ties, needs to play in two Davis Cup matches in the year before the 2012 Olympics to be eligible to compete in London.
"There will be a few decent matches and I'm looking forward to playing," said Murray, who meets Feliciano Lopez in the Wimbledon quarter-finals on Wednesday.
"It should be a fantastic atmosphere for the tie, and I'm hoping everyone back home gets behind the team."
Team captain Leon Smith added: "We're obviously very excited to have Andy in the team for the tie, any team in the world would love to have someone of his calibre.
"James Ward has played a key role in the last two Davis Cup wins and, with Colin and Jamie, we have two doubles players who are well established on the tour.
"We're all really looking forward to it and the team can't wait to play in front of a packed home crowd."
