The former World No. 1 was scheduled to play Auger-Aliassime
“I am really disappointed at having to withdraw, but the medical staff have advised me against playing in both events, so I have made the difficult decision to withdraw from the singles and focus on playing doubles,” Murray said according to Olympics.com.
The former World No. 1 is a two-time Olympic singles gold medalist (2012 and 2016). Murray teamed with Salisbury on Saturday to upset second seeds Pierre-Hugues Herbert and Nicolas Mahut of France in the first round of the doubles draw. The Britons will play Germans Kevin Krawietz and Tim Puetz in the second round.
Murray, who was scheduled to play Canadian Felix Auger-Aliassime in singles, was replaced by Australian Max Purcell. Hungarian Marton Fucsovics also withdrew (right shoulder), and he was replaced by Australian Luke Saville.
