Ash Barty has withdrawn from upcoming WTA events in Indian Wells and Miami, citing fitness setbacks.
The world No. 1 has not played since her historic singles victory at the Australian Open in January and is likely to remain out of action until April.
After sitting out the recent St Petersburg Ladies Trophy, Barty announced last week that she planned to participate at the Indian Wells Masters in California.
However, she has now withdrawn alongside Australian Open finalist Danielle Collins who is nursing a number of injuries.
In a statement released on the WTA website, Barty revealed she hopes to return in time for the Billie Jean King Cup qualifying event on April 15.
If all goes to plan, she will represent No. 1 seed Australia in a home tie against Slovakia.
"I wanted to share an update on my schedule for the coming months," Barty said.
"Unfortunately my body has not recovered the way I’d hoped after the Australian Open and I have not been able to adequately prepare for Indian Wells and Miami.
"I don’t believe I am at the level necessary to win these events and as a result I have decided to withdraw from both tournaments.
"I love these events and am sad not to be there competing but getting my body right must be my focus.
"My aim is to represent my country at the upcoming Billie Jean King Cup event in April.
"After missing the BJK Cup last year I can’t wait to wear the green and gold again."
The 25-year-old also paid tribute to those affected by floods in Australia and the ongoing invasion of Ukraine.
"On a more important note, it has been a tough few weeks at home in Australia and around the world," she said.
"I send all of my thoughts and best wishes to everyone in Queensland and New South Wales who have been affected by the devastating floods.
"To the people of Ukraine, especially my peers in the tennis family, we are all thinking of you and hope for peace.”
