Kerber to regain #1 ranking.
"Sadly, I have to withdraw from the BNP Paribas Open in Indian Wells and the Miami Open. I have not been able to train due to my knees and am disappointed I cannot be there. I will keep moving forward and continue to be positive. I look forward to being back as soon as I can."
Appears Serena will be withdrawing from not only the BNP Paribis Open but the Miami as well.
This will allow Kerber to regain # 1 WTA ranking.
A revised WTA draw will be updated shortly
