Andy Murray withdrew from the tennis singles at the Paris Olympics on Thursday but the two-time gold medallist will play doubles in what will be the final event of his glittering career.
The British former world number one, who will retire at the end of his fifth Games, has still not fully recovered from back surgery last month.
He believes the mens doubles, where he is playing with Dan Evans, offers his best chance of another medal.
Murray won gold in singles at London 2012 and in Rio four years later, as well as silver in mixed doubles with Laura Robson in 2012.
His withdrawal means his final singles match was his brief second-round appearance at Queens Club against Jordan Thompson last month before he was forced to pull out because of a spinal cyst.
The Scot confirmed earlier this week that he would retire after the Paris Olympics.
Murray has been ravaged by injuries in recent years, slumping to 121st in the world. He has played with a metal hip since 2019 and suffered ankle damage earlier this year.
Murray was only fit enough to play doubles with his brother, Jamie, at Wimbledon this month.
The three-time Grand Slam champion ended Britains 77-year wait for a mens champion at Wimbledon when he triumphed in 2013, defeating rival Novak Djokovic in the final.
He added a second title in 2016, taking his career majors total to three after breaking his duck at the 2012 US Open.
Murray won gold at the 2012 Olympics on an emotional day at the All England Club when he defeated Roger Federer just weeks after he had lost the Wimbledon final to the Swiss on the same Centre Court.
