Melbourne: U.S. Open champion Marin Cilic has withdrawn from this month`s Australian Open because of a shoulder injury, the world number nine said on Saturday.
The 26-year-old has been struggling with a right shoulder problem for more than a month and the Croatian skipped the Brisbane International in the hope of recovering in time for the season`s first grand slam beginning in Melbourne on Jan 19.
"I am really disappointed to announce that I had to withdraw from the Australian Open," Cilic said in a statement on his website.
"I was advised by doctors to be careful as much as possible to avoid even more serious problems.
"It is improving day by day, but I still don`t feel fit enough to be able to compete at the highest level."
