Andy Murray is still unable to return from his long-term hip injury but hopes to be back at Wimbledon.
Britain's Andy Murray has further delayed his return to tennis but hopes to be fit in time for Wimbledon next month.
The 31-year-old, who won the grass court grand slam title in 2013 and 2016, required hip surgery in Australia in January.
He has not played a match since last year's Wimbledon and was due to return at the s-Hertogenbosch Libema Open event in the Netherlands on June 11.
However, Murray says it has taken longer than expected for his hip to be match-fit but remains hopeful of beginning preparations for Wimbledon.
"I am not quite ready to return. I am still aiming to play in the coming weeks, but I want to be 100 per cent when I do return," said Murray.
"I've been out close to a year now, which is a lot longer than me or any of my team expected, but I'm getting closer to playing again.
"I've started training a few days ago and am hoping to make my comeback during the grass-court season."
