Great Britain start their Davis Cup Finals campaign against the United States in Glasgow on Wednesday as the competition's group stages begin.
Cameron Norrie, Dan Evans, Andy Murray, Joe Salisbury and Neal Skupski will compete for Britain, who have won the event 10 times, most recently in 2015.
Glasgow's Emirates Arena hosts the six Group D matches from 13-18 September.
A minute's silence will take place at the start of each day's play as a mark of respect following the death of Queen Elizabeth II, while the British team will wear black armbands or ribbons and the national anthem will be played.
