Maria Sharapova is confident of being fit for January's Australian Open despite pulling out of the Brisbane International with an ankle injury.
The Brisbane International is a warm-up event for the Australian Open, which begins on 16 January.
The Russian former world number one said: "Unfortunately my ankle is not 100% and I won't be able to make it.
"I do expect to be ready for the year's first Grand Slam and I am really looking forward to competing on court."
Sharapova, who has won Wimbledon and the US Open, clinched the last of her three Grand Slam singles titles at Melbourne Park in 2008.
However, she was beaten in the fourth round of the 2011 tournament by Germany's Andrea Petkovic.
