Naomi Osaka’s season appears to be over after she said she will not play at next month’s Billie Jean King Cup finals because of injury.
The four-time Grand Slam singles champion said in Tokyo on Sunday that she had ruptured abdominal muscles.
“I thought I strained my back, but I did an MRI in Beijing and they said that I bulged a disc in my back and I also ruptured abdominal muscles,” Japan’s Kyodo News agency reported the 27-year-old as saying.
Osaka has been sidelined since she retired from her last-16 match at the China Open against eventual champion Coco Gauff at the start of the month.
