Andy Murray says he hopes to return to play singles tennis before the end of the year, but doesn't think he'll be ready in time for the US Open.
The former world number one had hip resurfacing surgery in January in a bid to save his career and he's set to play in the doubles at Queen's Club this week.
Murray admits he has "quite a lot of work to do" to get back playing competitive tennis, having not played since his defeat to Roberto Bautista Agut in the opening round of the Australian Open in January.
"I'm feeling good, pretty much pain free and enjoying just training, practising, improving all the time just now.
"I don't think when Wimbledon finishes that I will just step on to the singles court the following week and everything's good.
"At this moment I've been progressing all of the time. At some stage it's probably going to plateau for a while before I'm able to kick on.
"I hope at some stage this year I would be able to get back to playing singles again. I'm not really interested in putting a time limit on it because I'm quite happy just now.
"So I don't need to play singles after Wimbledon or at the US Open to - you know, enjoy doing what I'm doing just now.
"If I can, that would be brilliant, but I don't think that's going to be the case. I think it's going to take a bit longer."
