Australian showman Nick Kyrgios conceded Wednesday his tennis career could be over, but said: "I'm OK with that". The talented but temperamental 28-year-old had knee surgery a year ago, then aborted plans to return at Wimbledon after tearing a ligament in his wrist. 

He withdrew ahead of the Australian Open as he continues to struggle for fitness, but is at the Grand Slam in Melbourne as a commentator. He conducted the on-court interview after defending champion Novak Djokovic beat Taylor Fritz to reach the semi-finals on Tuesday. Kyrgios said a career in the media was looking increasingly attractive. "I sat down with my agent, Stuart Duguid, a couple of days ago to talk about my future," he wrote in a column for The Age newspaper in Melbourne.
