Caroline Wozniacki injury doubt for Australian Open

Caroline Wozniacki has emerged as an injury doubt for the upcoming Australian Open after suffering a wrist problem at the Sydney International.

The world number one had her wrist strapped in the third set of her 3-6 7-5 6-2 defeat to Agnieszka Radwanska.

"I'm going to get it checked out tomorrow and hopefully it's okay. Let's just hope for the best," she said.

"I hope it's not serious. I could feel it today, especially in the third set. I should be completely fine for Australian Open."

Wozniacki will lose her number one spot in the rankings should Petra Kvitova win the Sydney tournament.
