Andy Murray is right to rest and not play in this week's Davis Cup quarter-final against Serbia in Belgrade, says captain Leon Smith.
The Wimbledon champion has not missed a Davis Cup tie for over three years.
But Smith said: "Quite rightly he has to look after his body and his mind. He's got his eyes set on getting some rest and really making a big push for the Olympics, US Open and beyond."
Kyle Edmund and James Ward will play singles for holders Great Britain.
The quarter-final begins on clay in the Tasmajdan Stadium on Friday.
