LONDON, Oct. 18 (Kyodo)—Rising teenager Kei Nishikori will miss the remainder of this season due to a knee injury, his management office said Saturday.
Nishikori, who climbed to 66th in the ATP rankings after reaching the semifinals of the Stockholm Open last week, received treatment on his right knee after returning to his training camp in Florida.
Although there was no serious injury detected after the 18-year-old underwent an MRI, it was determined that he should sit out the rest of the season in order to return to full form.
Nishikori became the second Japanese to win a tournament on the men's top-tier circuit with his victory in February at the Delray Beach International in Florida.
He is the second-highest ranking Japanese after Shuzo Matsuoka, who achieved the highest-ever ranking by a Japanese man under the computerized world rankings established in 1973 with 46th place in July 1992.
Have a good rest and start the 2009 season fit and strong, Kei!
