Sabalenka would have been the top seed for the tournament, which begins on Wednesday.
World number two Aryna Sabalenka has been ruled out of next week’s BNP Paribas Open in Indian Wells after testing positive for coronavirus.
The Belarusian would have been the top seed in the absence of Ashleigh Barty who decided to head back to Australia having not been home since March.
In 'n Instagram-plasing, Sabalenka wrote: “Unfortunately I’ve tested positive at Indian Wells and won’t be able to compete. I’ve started my isolation and I’ll be staying here until I’m cleared by the doctors and health officials. So far I’m feeling OK but really sad to not be able to play this year.”
The 23-year-old is one of a number of tennis players to have publicly expressed hesitancy about receiving the vaccine, saying earlier this year that she did not trust it.
The women’s draw will also be missing Naomi Osaka who is taking another break from the sport.
