He faces Australian qualifier Alex Bolt in his first round match on Tuesday.
Just hours later, Murray dropped his bombshell, ending his hopes of adding another Wimbledon crown to those he collected in 2013 and 2016.
He has played three matches since returning to competitive action, losing against Nick Kyrgios at Queen's then beating Stan Wawrinka in Eastbourne before losing against fellow Briton Kyle Edmund. Murray also won the 2012 U.S. Open and two Olympic singles gold medals.
He is next scheduled to play in Washington beginning on Jul 30.
"We did everything we could to try and be ready in time".
Murray, 31, had looked likely to play this fortnight at the All England Club, but on Sunday shocked the tennis world by suddenly announcing he was pulling out because he did not feel he could compete properly, and wanted to concentrate on being ready for the USA hard-court season. "Thanks for all the messages of support and I'm excited to finally be back playing after so long out".
Murray's place in the draw goes to Jason Jung of Taiwan, the world numner 154 who has just one win on the main tour in 2018.
The Scot took to Facebook to announce the sad news that he simply wasn't ready to make the step up to best of five set matches.
But all of his time away meant the former No. 1-ranked Murray has fallen out of the top 150 and he was not seeded at Wimbledon. I am taking it literally each day. "In fact, I feel like it's stronger because I've been through so much", she told the official website of the championships. He is not at his best following hip injury, as explained by him in press conference: 'There're certain things that are still tricky and things I'm still trying to work through.
"I'm pumped. Four or five weeks ago, I didn't know whether I'd be capable of competing at a level I'd be happy with".
