Former champion Rafael Nadal withdrew from the Aegon Championships at Queen's on doctor’s advice, but insisted he would be fit for Wimbledon.
Nadal, who won his 10th French Open on Sunday, said: "“I am very sorry to say that I am not going to be able play Queen’s next week. I was hoping to take some days off and then be ready. But, at 31, and after a long clay-court season with all of the emotions of Roland Garros, and after speaking to my team and doctor, I have decided my body needs to rest if I am going to be ready to play Wimbledon.”
The current world number two won Wimbledon in 2008 and 2010.
The announcement ahead of Monday’s Aegon Championships came as a surprise, and casts doubt on his chances of winning a third title at Wimbledon, which starts on July 3.
"I am sad to make this decision because I love Queen's, I won the tournament in 2008 and every time I reached the Wimbledon final it was after playing Queen's," he added.
Britain's Andy Murray, the world number one, will defend his title at the Aegon Championships.
The field will feature several of the world's top players including Stan Wawrinka, Milos Raonic, Juan Martín del Potro, Nick Kyrgios, Jo-Wilfried Tsonga and Marin Cilic.
