"I'm sick, basically," she said in a press conference. "It's a short story. Just not feeling well. I had a fever. Yeah, I just don't feel well. Gonna go back to bed and rest up."

Wozniacki was set to take on Czech qualifier Karolina Muchova later on Tuesday, and will be replaced by lucky loser and 2011 US Open champion Samantha Stosur. 

"It's definitely frustrating. I have been here for quite a few days practicing and just trying my best to be prepared and ready to go today. I already felt it last night, but I woke up today and didn't feel well at all. Sometimes you have to make those decisions and just need to rest up."

The Dane last played at the Australian Open where, as defending champion, she fell in three sets to fellow former World No.1 Maria Sharapova. She aims to be back in action in time for next week's Dubai Duty Free Tennis Championships, a tournament she won in 2011 and finished runner-up in 2017.

Caroline Garcia has also withdrawn from the tournament citing a leg injury. Due to play Lesia Tsurenko, the French star has been replaced by lucky loser Lara Arruabarrena; the winner will play top seed Simona Halep

"I played FC this weekened and I arrived this morning very early," Garcia informed the press. "When I warm up, I feel pain in my left quad - I was not feeling comfortable with it and it was getting worse through the practice. I had to play in one hour and it was too short to make any recovery."
