The Australian withdrew from his first round match against Donald Young at Queen’s Club after losing the first set in a tiebreaker, having slipped awkwardly with the scores at 4-4.

The fall aggravated a previous hip condition which Kyrgios has been nursing but he remained hopeful he’d be injury-free for Wimbledon, which starts on July 3.

"Obviously my main goal is to play well at Wimbledon, so I'm going to try and get it better and rehab it and hopefully it settles down,” Kyrgios said.

"I'm not going to get a scan, as yet. I got the injections a couple weeks ago and then I was in rehab for a couple of weeks.

"It settled down and then on that fall I just felt sharp pain. I felt pretty much everything I was feeling a month ago.

"It's not great at the moment but we'll see."
