Nick Kyrgios says he will give himself every chance to be ready for Wimbledon after withdrawing from the Halle Open with an ongoing knee problem.
The Australian, 28, underwent surgery on his left knee earlier this year.
Runner-up at the All England Club last year, Kyrgios has played just one match in the past five months.
"As you all know, that tournament [Wimbledon] means a lot to me and I just want to do everything right by my body," Kyrgios added.
Kyrgios suffered a first-round loss to China's Wu Yibing at the Stuttgart Open last week, struggling with his movement during a straight-set defeat.
