Andy Murray is doing "everything he can" to be fit for Wimbledon, according to his mother Judy.
The two-time Wimbledon champion has been sidelined since last year's tournament and underwent hip surgery in January.
Murray's mother Judy has insisted the 30-year-old can still be ready to hit form come Wimbledon's July 2 start.
"His goal was always to be ready for the grass-court season and, fingers crossed, that will happen," said Judy Murray.
"I'm sure when he's got some news he will share that."
Murray is unlikely to feature in a tournament in Loughborough later this month, while the Scot has publicly committed himself to Holland's Rosmalen grass court tournament that starts on June 11.
"The strength and depth of men's tennis is so great that I don't think anybody would want to come back into that environment unless you are 100 per cent," said Judy Murray.
Asked if she had any fears about his career being over, the former Fed Cup captain added: "I don't think so - he's still got a lot of things he wants to achieve in the game."
Meanwhile, Britain's Kyle Edmund reflected on "lots of good things" after he moved into the quarter-finals of the Madrid Open.
The 23-year-old followed up his victory over 12-time Grand Slam champion Novak Djokovic in the previous round by sweeping past last-16 opponent David Goffin.
Edmund's 6-3 6-3 win booked a last-eight clash against Canadian Denis Shapovalov, who beat Milos Raonic 6-4 6-4.
The victory also means that Edmund will secure a place in the world's top 20, and the formbook reads in his favour for the next round as he beat Shapovalov when they last met at the Brisbane International earlier this year.
"There were lots of good things. I managed my game very well," said Edmund.
"My game is one of those where the better I manage it and pick my moments to be aggressive, then I play well.
"I served really well. It got me through easy games and also got me out of some tricky situations.
"He is a top player, top 10 in the world, so it is very pleasing."
Edmund built on the Djokovic display in emphatic fashion, taking control from the opening game, when he broke World No.10 Goffin's serve.
He then kept the Belgian on the back foot throughout and forced several errors from his opponent.
After breaking Goffin's serve in the opening game, Edmund went on to lose just four points in his first four service games and took the set in 32 minutes.
Edmund saved two break points on his first service game in set two, digging deep as Goffin tried to force his way back into the contest.
On the women's side, World No.1 Simona Halep's Madrid Open hat-trick hopes bit the dust as she was overpowered 6-4 6-3 in the quarter-final by inspired Czech Karolina Pliskova.
Dutch star Kiki Bertens continued her impressive week as she backed up a third-round win over World No.2 Caroline Wozniacki to beat Maria Sharapova in the quarter-finals.
Unseeded Bertens recovered from losing the first set to win 4-6 6-2 6-3 and set up a semi-final with Caroline Garcia, who eased past local hopeful Carla Suarez Navarro 6-2 6-3.
