Britain's Andy Murray has delayed his comeback from surgery but still hopes to play at Wimbledon in July.
The 31-year-old Scot, who has not played since Wimbledon last year, had a hip operation in January.
He had hoped to play in the grass-court Libema Open in the 's-Hertogenbosch, the Netherlands, starting on 11 June.
"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.
