Australian Open fans were disappointed after local favourite Nick Kyrgios was forced to withdraw from the tournament owing to injury before even taking to the court. The 27-year-old announced he was dropping out because of an injured left knee that needs arthroscopic surgery. Kyrgios was the runner-up at Wimbledon last year in singles and the men’s doubles champion at the Australian Open and was considered the host country’s strongest chance to win a title at Melbourne Park this year.
