Kyle Edmund and James Ward have both been named in Great Britain's Davis Cup team alongside Jamie and Andy Murray for this week's final against Belgium.
Captain Leon Smith's decision to include the pair has resulted in Dom Inglot missing out on a place in the final, which gets underway on Friday in Ghent.
Edmund, who is ranked 100th in the world, will be making his Davis Cup debut for Britain, who have reached the final for the first time since 1978.
The 20-year-old will open proceedings with a singles rubber against David Goffin on Friday, with his teammate Andy Murray taking on Ruben Bemelmans in the second match of the day.
On Saturday, Steve Darcis and Kimmer Coppejans will face the Murray brothers in the doubles, while Andy and Edmund will be in action again on Sunday taking on Goffin and Bemelmans respectively.
The personnel for matches can be switched up until an hour before each day's play.
