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 No 1, who will retire at the end of his fifth Games, has still not fully recovered from back surgery last month.
He believes the men's doubles, where he is playing with Dan Evans, offers his best chance of another medal.
"I've taken the decision to withdraw from the singles to concentrate on the doubles with Dan," said the 37-year-old.
"Our practice has been great and we're playing well together. Really looking forward to getting started and representing GB one more time."
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 Queen's 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.
"The Olympics are incredibly special for me, had some amazing memories on the court in London in 2012," he said at Roland Garros on Thursday.
"Playing at home and winning medals was unbelievable. I am happy to do it one more time to compete for my country.
"I trained the last few weeks to get myself ready to play singles and doubles but I am getting older and it's harder to recover from all the injuries. I just ran out of time. But I am happy to be in the doubles with Dan – we can have a good run."
RAVAGED BY INJURIES
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 Britain's 77-year wait for a men's 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.
Four years later, he defeated Juan Martin del Potro to become the first tennis player, male or female, to win two Olympic singles golds.
Murray also led Britain to the Davis Cup title in 2015, the country's first in 79 years.
He has won 46 titles in all and banked around $65 million in prize money.
