Nishikori out of Oz Open

A day after Andy Murray put his Grand Slam comeback on hold, Japan’s Kei Nishikori has become the latest high-profile player to withdraw from next month’s Australian Open, citing a right elbow injury. Tennis Australia issued a statement saying Nishikori had withdrawn from the season-opening major at Melbourne Park and from the ATP Cup next week which will be played in Sydney, Perth and Brisbane.
