Andy Murray withdrew from the singles after consultation with medical staff due to a quad strain but will continue to compete in the men’s doubles alongside Joe Salisbury.
This is due to a minor thigh strain and as a result, will not defend his Olympic title.
Andy Murray, who won singles’ gold in 2012 and 2016.
In a press release, he said, “I am really disappointed at having to withdraw but the medical staff has advised me against playing in both events,” he said in a statement. “So, I have made the difficult decision to withdraw from the singles and focus on playing doubles with Joe.”
He was due to face ninth-seed Felix Auger-Aliassime from Canada in the first round of the men’s singles, but was replaced on the order of play by Australian Max Purcell.
Murray won consecutive matches at Grand Slam level for the first time in four years on his Wimbledon singles return last month, before he lost to eventual semi-finalist Denis Shapovalov.
He’s the only tennis player ever to win back-to-back singles gold medals.
