The agent for the 2014 runner-up and 2016 semifinalist at Flushing Meadows said Wednesday that Nishikori will miss the rest of the season because of a torn tendon in his right wrist. Yesterday, we went to see a very renowned wrist specialist who works with numerous MLB baseball pitchers. And unfortunately he has torn a tendon. Nishikori will wear a cast on his wrist and, after the swelling reduces in the coming weeks, "we will evaluate next steps", Van Lindonk said. "Kei will withdraw from all the 2017 tournaments and work hard to be ready for next year".
Nishikori will miss the US Open, his most successful major, for the first time since 2009.
The 27-year-old has been suffering from pain in his right wrist on and off this year. Nishikori withdrew from Barcelona and conceded walkover in the Madrid quarterfinals in May due to the injury.
Nishikori joined defending champion Stan Wawrinka and three-time victor Novak Djokovic in deciding to sit out the U.S. Open, which starts August 28.
Fourth-ranked Stan Wawrinka and number five Novak Djokovic have in recent weeks called a halt to their seasons to recover from knee and elbow injuries respectively.
Djokovic, Wawrinka, Andy Murray, Roger Federer, Marin Cilic and Milos Raonic are the other top players missing in Cincinnati.
Nishikori, ranked ninth in the world, withdrew Sunday from the ongoing Western and Southern Open, a tuneup to the U.S. Open starting late this month in NY, after experiencing pain in his right wrist during practice. Milos is seeing doctors today as we speak in NY.
Nishikori's withdrawal gives Thiago Monteiro entry into the main draw.
