Davis Cup captain Leon Smith has confirmed Andy Murray will not compete for Great Britain in this weekend's tie against Canada.
Smith left the door open for the world number one who had intimated he needed time to recuperate.
"It's the right thing for him to do what he's doing, stay at home, get some rest," said Smith.
Dan Evans, Kyle Edmund, Jamie Murray and Dom Inglot make up Britain's team for their first-round tie.
Smith added: "We've got so much confidence in what they can do.
