Reigning Wimbledon champion Barbora Krejcikova has withdrawn from the BNP Paribas Open and Miami Open due to her continuing back injury. The 29-year-old Czech has not played a tournament since the WTA Finals in Riyadh in November, where she won over Coco Gauff and Jessica Pegula before falling to Zheng Qinwen in the semifinals. 

With Krejcikova's withdrawal, Austria's Julia Grabher has moved into the main draw at Indian Wells. Click here for the updated entry list.
