The long-term goal for Murray is to return to the ATP tour where he climbed to No 1 in the world and won three Grand Slam titles.
However, he is cautious of not rushing back from the career-threatening hip injury which required surgery in January.
To ease himself back into things, Murray is playing mixed doubles at Wimbledon this week in a blockbuster pairing with Serena Williams.
The duo has stormed through their opening two rounds in straight sets – Fabrice Martin and Raquel Atawo the latest victims this evening.
Murray was then quizzed on how far away he is from a full recovery after showing glimpses of his former self on Centre Court.
But he has ruled out returning to best-of-five single’s matches in 2019.
“I think it’s pretty unlikely just in terms of timing,” Murray said.
“I spoke to my team a bit about that yesterday. Just a lot of stuff I need to get done physically, get myself stronger.
“The amount of work I need to do on the court to get ready for singles, the amount of work I need to put in off the court to get myself strong enough to play best-of-five sets, it’s still quite a ways away unfortunately.
“I would love to play. I need to look, like, pretty long-term with this. I don’t want to be having to go through another big operation in a few years’ time.
“I want to make sure the operation I’ve had lasts for as long as possible. To give it the best chance, I need to make sure that, I’m physically, you know, really strong before I get back on the singles court.”
The American hard-court swing kicks-off a few weeks after the Wimbledon final – which Murray and Williams hope to be involved in.
But the Brit is yet to decide what his schedule will look like going forward.
“I don’t know. I might take a break. I might train and play doubles. I might just train for singles. I really don’t know,” he added.
“I think what I’ve done this grass court season has been a positive thing and has been the right decision kind of for my hip to see kind of where I’m at. I can’t say exactly just now.”
The 32-year-old also ruled out competing at any smaller events in the singles, suggesting doubles is the way forward for the rest of the year.
“No. Right now it’s not, no,” he said.
“I want to try to prepare to try and get ready for singles. If I’m able to train the way that I need to off the court and still maintain kind of, I guess, my performance on it in doubles, I would consider that.
“But, you know, also, yeah, I don’t know if I want to go over to the States to play doubles for four or five weeks. I’m not sure. I’m not sure yet. I’ll decide on that probably when the tournament’s done and sit down with my team.
“But having felt how I felt these last few weeks, I’m positive about the future, so therefore I’m going to train properly to try and give singles a go. But that will take time.”
