Andy Murray will give the first public indication of whether he has fully recovered from a hip injury when he takes on Roger Federer in a charity match in Glasgow on Tuesday.
The Briton, 30, last played on 12 July when he lost to American Sam Querrey in the Wimbledon quarter-finals.
Murray was forced to withdraw on the eve of the US Open in August because the injury remained an issue.
He has dropped from first to 16th in the world rankings since Wimbledon.
The Scot will face Federer as part of the Andy Murray Live exhibition on Tuesday to raise funds for a variety of charities.
Murray will also team up with his brother Jamie to take on Tim Henman and Mansour Bahrami in a doubles match.
World number two Federer, 36, will be making his first appearance in Scotland as he prepares for next week’s ATP World Tour Finals in London.
