Maria has pulled out of the Brisbane International due to collarbone injury.

Here is what Maria said on Facebook:
On another note, I won't be able to play in Brisbane this year unfortunately. My collar bone is feeling so much better but just didn't have enough days to fully prepare for the tournament. For the few days I have been here, what a nice tournament and atmosphere! Now on to the Australian Open...I'm so excited!

The Australian Open begins on January 14th.
