Andy Murray pulls out of planned return, hopeful over Wimbledon

Murray, who hasn't played since Wimbledon last year, had an operation on his hip in January.

The 31-year-old had planned to play his first grass tournament of the year at the Libema Open in 's-Hertogenbosch, Netherlands, which begins on June 11.

"I am not quite ready to return. I am still aiming to play in the coming weeks, but I want to be 100% when I do return," said Murray.

"It is with regret that I won't be ready to play in Hertogenbosch. I was excited to play there for the first time.

"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," added Murray.

Murray has won Wimbledon twice before - in 2013 and 2016 - and will need to be back in time before the tournament begins on July 2.

The former British number one usually plays at Queen's Club in the build-up to Wimbledon, and that takes place from June 18-24, though it is unclear whether he will be fit enough to participate.
