Here's an article on it:
Japan's hottest tennis prospect, Kei Nishikori, will skip the Davis Cup tie against Australia in Brisbane next month as he has not fully recovered from injury, the national tennis association said Monday.
The 20 year old, who returned to competition in February after an 11-month lay-off, is instead preparing to take part in the French Open around two weeks later.
The Japan Tennis Association, in announcing the squad against Australia, said it had passed over Nishikori as "his recovery is not complete".
Nishikori said on his website last week he would compete in the French Open after two claycourt events in the United States in the coming weeks.
The player, after reaching his personal best 56th spot in the world rankings in February last year, suffered a stress fracture a month later. He underwent surgery in August and resumed training in late October.
The Japan squad against Australia includes Go Soeda, Yuichi Sugita, Tatsuma Ito and Takao Suzuki, whose world rankings are 184th, 200th, 256th and 315th respectively.
Japan beat the Philippines 5-0 in the first round.
Australia's team will be announced on Tuesday with former world No.1 Lleyton Hewitt expected to be included.
Australia last met Japan in 1996, winning 4-1 and lead Japan 14-2 in the Davis Cup, having won their past six encounters.
The winners of the May 7–9 Davis Cup Asia–Oceania second-round tie in Brisbane, to be played on a purpose-built clay court, will advance to the World Group promotion/relegation play-offs in September.
