Ana has withdrawn from the Internationaux de Strasbourg due to inflammation in her left wrist.
She said: "It's very disappointing. It's always extra disappointing to have to withdraw while on-site at a tournament, because you've felt the excitement and met the staff, and you're looking forward to being part of it all.
"I was impressed by this tournament while I was here, I felt very welcome, and it's such a shame that I am unable to compete. Hopefully I'll be back sometime in the future.
"I've had this pain for a while now, despite physical therapy. My doctor has told me to rest it completely for a few days, and I'm having treatments twice a day.
"Considering that it is not my racket hand, I can still practice, but backhands are out of the question for the next few days. I expect to be fit for Roland Garros."
