In the past, she has had major problems with a back injury. It kept her out of action in three out of four majors last year. But now it appeared to be the one thigh that was bothering the 26-year-old.
– I feel so much for her. I really hope she recovers quickly and is ready to play in Madrid, said Aryna Sabalenka.
The WTA 1000 tournament in Madrid begins on April 23.
