Five-time Australian Open finalist Andy Murray on Thursday said he would head home after pulling out of the first tennis Grand Slam tournament of the year due to an ongoing hip problem that has kept the former World No.1 from competitions since mid-way through last year.The lingering injury forced the British player, now ranked 16th, to withdraw from Brisbane International on Tuesday, cancelling his match against Ryan Harrison of the United States, reports Efe."Sadly, I won't be playing in Melbourne this year, as I am not yet ready to compete," said Murray.Murray, who is considering surgery on his hip, played his last official match in July, when he lost to Sam Querrey of the US, 3-6, 6-4, 6-7 (4), 6-1, 6-1 at the Wimbledon quarterfinals."I'll be flying home shortly to assess all the options but I appreciate all the messages of support and I hope to be back playing soon," the 30-year-old Scot stated.Meanwhile, Australian Open Tournament Director Craig Tiley said Murray had been suffering with his hip, wishing him, "the absolute best on his road to recovery."Earlier in the day, Japan's Kei Nishikori announced he would miss the Australian Open because of a right wrist injury.
