Former US Open finalist Kei Nishikori will miss the last Grand Slam of the season after tearing a tendon in his right wrist. The injury will keep him sidelined for the remainder of the year.

The 27-year-old Japanese reached the championship match in New York in 2014, falling to Marin Cilic in each player's first major final.

Nishikori’s best Grand Slam results have been in Flushing Meadows, where he also reached the semifinals 12 months ago. He has never been past the quarterfinals at any other major, falling in the round of 8 three times in Melbourne and twice in Paris.

Nishikori becomes the third Top 10 player to withdraw from the US Open, following two-time winner Novak Djokovic (elbow) and reigning champion Stan Wawrinka (knee).

In a statement from Nishikori’s team, a spokesman said he sought advice from five wrist specialists and hopes to be back in 2018.

“Two days ago during practice in Cincinnati, Kei hit a serve and heard a 'pop' in his wrist,” the statement read. “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 specialist.

“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.”

Nishikori’s withdrawal moves Thiago Monteiro into the main draw.

The US Open takes place from Aug. 28 - Sept. 10.
