Murray has been giving himself as long as possible to be ready to play in what will be an emotional goodbye at the scene of some of his greatest triumphs, having also won Olympic gold on Centre Court at London 2012.
The Scot’s plans have been disrupted by the back issue which flared up earlier this summer and forced him to retire from his match at Queen’s against Australia’s Jordan Thompson on 19 June after only five games.
But he has fought to be fit because he wants a bit of “closure” at the All England Club before stopping playing professionally.
On Sunday, Murray said the area where he had the operation was not sore, but added he still did not have 100% feeling in his leg.
He trained with former British number one Kyle Edmund for more than an hour on Monday, leading 6-3 2-0 in a practice match before they stopped.
Afterwards, Murray said he would make a decision later that evening and announced on Tuesday morning – several hours before he was due to face Machac – that he would focus on the doubles.
The Murray brothers have never played together at the Championships.
Andy and 38-year-old Jamie represented Great Britain in doubles at the London 2012 Olympic Games at the All England Club, when they lost in the first round.
