Kei Nishikori will miss the Asian Swing — his hometown tournament, Tokyo and Shanghai — due to an arm injury that he has had on and off since May.
The much anticipated exhibition match between Nishikori and Roger Federer on October 14 in Tokyo is also canceled.
If things go according plan, Nishikori plans to play Vienna and Paris. He is in the running for the year-end ATP finals in London. Nishikori has committed to play Davis Cup later this year.
