Defending champion Andy Murray has pulled out of his final warm-up match before Wimbledon because of a sore hip.
The world number one, 30, was scheduled to play an exhibition match at Hurlingham Club in London on Friday.
"Sadly I won't be ready to play at the Hurlingham, my hip is still sore and I need to rest it," he said.
The Briton is still expected to begin the defence of his Wimbledon title on Monday, but will be short of practice heading into the Championships.
Murray has only played one grass-court match this year, suffering a shock first-round defeat by world number 90 Jordan Thompson at Queen's.
