World number nine Kei Nishikori will miss the rest of the 2017 season after tearing a tendon in his right wrist.

The Japanese player's manager announced the news on Wednesday, just days after Nishikori was forced to pull out of the Cincinnati Masters.

The 27-year-old joins a number of high-ranked players to take time out from the sport due to injury this season.

Stan Wawrinka and Novak Djokovic, currently ranked four and five in the ATP ladder, have in recent weeks called a halt to their seasons to recover from knee and elbow injuries respectively.

And world number one Andy Murray will lose his coveted top ranking this week after missing every event following Wimbledon with a troublesome hip problem.

Nishikori felt a sharp pain in his wrist during practice for the Cincinnati event on Sunday.

"Kei hit a serve and heard a 'pop' in his wrist," his manager said in a statement. "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."
