Kei Nishikori, the 2014 U.S. Open runner-up, will have arthroscopic surgery on his left hip this week and be sidelined for about six months.
Nishikori posted a message on his app saying he tried “several different rehab options” before deciding with his medical team to go ahead with the operation.
The 32-year-old from Japan sat out the Australian Open and has not played on tour since a second-round loss to Dan Evans at Indian Wells in October. Nishikori lost to Novak Djokovic in the third round of the U.S. Open in September.
Nishikori reached the final at Flushing Meadows in 2014 before losing to Marin Cilic. The next year, Nishikori reached a career-high ranking of No. 4. He is currently No. 46.
The post said: “I will work as hard as I can and the goal is to be back in about 6 months.”
