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.
