Nick Kyrgios has confirmed that his 2017 campaign has come to an end because of a hip injury.
The 22-year-old accepted that he had no option but to end his season prematurely if he has any chance of being fit and ready to be fully fit for the start of 2018 and a tilt at his home Grand Slam, the Australian Open in January.
Kyrgios has endured a difficult spell over the past month as he was hit with a point penalty in his China Open final defeat against Rafael Nadal, before leaving the court midway through his first-round match at the Shanghai Masters which saw him hit with a $1,000 fine.
A second-round defeat against home favourite Ruben Bemelmans in Antwerp on Wednesday will be the final action of the campaign for Kyrgios, who also reached the final of the Cincinnati Masters and helped Australia reach the Davis Cup semi-finals this year.
"Unfortunately due to the reoccurrence of my hip injury which I originally suffered at Queen's, I am shutting down my season to make sure I can rehab and prepare as best as I possibly can for the Australian summer," Kyrgios said in a statement on Twitter.
"Unless I want this to escalate into an injury that requires surgery, I need to listen to my body and my team."
He added: "This year hasn't been as successful as I would have liked, especially at the Slams.
"It's no secret that I have had some sad moments to deal with away from the court [his grandfather's death] which have added to my disappointments throughout the year."
Kyrgios' announcement followed on from world number 18 Tomas Berdych prematurely ending his year because of a back problem, while Andy Murray, Novak Djokovic, Stan Wawrinka and Kei Nishikori are also sidelined until the New Year.
