There are fears that Andy Murray could be set to miss the entirety of the upcoming grass court season, despite submitting his entry to the Queen's tournament.

The Telegraph are reporting that Murray's fitness battle, which has beleaguered him for almost a calendar year, could see him forced to sit out events on grass this summer, including the biggest one of them all, Wimbledon.

Murray's summer grass court commitments should have included not only Queen's, but also the Rosmalen event in Holland, which would see him up his preparations ahead of the Grand Slam at the All England Club, which commences in mid-July.

The 30-year-old's last competitive match was 10 months ago - which came in a Wimbledon defeat to Sam Querrey.

A hip injury ended his season, which he had surgery for in January to resolve a long-standing issue. With Murray's rehabilitation well underway, the target was a Wimbledon return.

The injury outlook for Murray has failed to improve, with questions now being raised about his future.

Murray's absence from the sport has seen the two-time Wimbledon champion slip down the rankings, and subsequently being displaced as the number one British man following the emergence of Kyle Edmund.

Murray's close friend and long-term rival, Rafael Nadal, who himself has suffered from lengthy knee injury issues in the past, reassured the Scot that he is not alone when it comes to niggling worries.

“I have been in that situation. I know how tough and frustrating it is when you work every day and you don’t see any improvements.”

The Lawn Tennis Association were hoping that Murray would return in time for their new Challenger event in Glasgow, while a second event at Loughborough also takes place this summer. The two events have cost the LTA a reported £400,000.

“Wimbledon is such a long way off,” a source close to the championships at the Queens Club in west London said, “nearly two months, in fact, it seems premature to be writing him off."
