Former world No.1 Maria Sharapova will miss next month's BNP Paribas Open at Indian Wells due to a right shoulder injury, organisers said on Wednesday.
The shoulder problem had also forced the 31-year-old to withdraw from her second-round match in St Petersburg, Russia, last month.
"We will miss Maria this year and hope to see her back at Indian Wells next year!" the tournament organisers said on Twitter.
Sharapova's withdrawal allowed German Mona Barthel to secure a spot in the Indian Wells singles draw. The tournament will take place from March 4 to 17.
