Caroline Wozniacki has withdrawn from the Kremlin Cup in Moscow next week, the Danish media reports.

The 2012 Moscow champion is no longer listed in the Kremlin Cup draw. Wozniacki is scheduled to play the WTA Finals in Singapore, which begin the week of Oct. 20.

Wozniacki's withdrawal comes after both Eugenie Bouchard and Ana Ivanovic pulled out of Linz. The sixth-ranked Bouchard is battling a left leg injury.

“It’s hard for me to keep playing and keep making it worse," Bouchard said. “The plan is to take a lot of days off right now and really rest. The goal is to try play Singapore in a week and a half. I won’t have ideal training probably but I’ll give it my best.”

Ivanovic withdrew with a left hip problem. “The injury has been plaguing me the whole summer, and it got worse during the recent tournaments in Asia," Ivanovic said in a statement.
