Kei Nishikori has confirmed he will miss the rest of the tennis season due to injury.
The World No 9 withdrew from this week's Masters event in Cincinnati with a right wrist problem. Unfortunately, subsequent scans revealed a tear in one of the tendons.
While he hopes to avoid surgery, the Japanese star has been ruled out for the remainder of 2017, joining fellow top-10 players Novak Djokovic and Stan Wawrinka on the sidelines.
It's been a tough season for Nishikori, who has struggled with injuries, causing him to slip five places down the rankings.
A statement from Nishikori's manager read: "Two days ago during practice in Cincinnati, Kei hit a serve and heard a 'pop' in his wrist.
"We went straight to the hospital to take an MRI. Yesterday, we went to see a very renowned wrist specialist who works with many of the MLB baseball pitchers.
"We saw another specialist today to get a second opinion. On top of that we have sent MRI results to three other wrist specialists to ensure we get several independent opinions from specialists.
"After consulting with all of them, it has become clear that Kei has a tear in one of the tendons in the right wrist.
"At this stage we have elected not to do surgery and Kei is in a cast. After the swelling comes down in the next weeks, we will evaluate next steps. Kei will withdraw from all the 2017 tournaments and work hard to be ready for next year."
