Nishikori Withdraws From ATP Cup
“Today, together with my team, we have made this decision as I am still not 100 percent ready to compete at the highest level,” Nishikori said in a statement.
Nishikori has not competed since this year’s US Open due to a right elbow injury that he underwent surgery for in October. Yoshihito Nishioka will replace him as the top-ranked player in Japan's lineup. Yasutaka Uchiyama also withdrew from the event earlier this week and was replaced by Toshihide Matsui.
