Debutant Kyle Edmund has joined Andy Murray, Jamie Murray and James Ward in Great Britain's team for the Davis Cup final against Belgium.
Doubles specialist Dominic Inglot misses out, with GB electing to go for three singles players.
British number two Edmund, 20, could be the first player since Spain's Feliciano Lopez in 2003 to make his Davis Cup debut in the final.
Great Britain are in the final for the first time since 1978.
Leon Smith's team are hoping to win Britain's first Davis Cup since 1936, while Belgium have yet to win the competition.
