US Open champion Naomi Osaka has pulled out of this week’s Hong Kong Open to prevent aggravating a slight back injury, organizers said on Sunday.
The Japanese star required treatment to her lower back during her semi-final defeat to unseeded Anastasija Sevastova at the China Open in Beijing on Saturday.
Afterwards, Osaka, who turns 21 on October 16, said it was more a case of fatigue than anything more serious, but suggested that she may not make the WTA Hong Kong Open, which starts on Monday.
“Unfortunately, I have been playing through pain in my back this whole week,” the world number six said in a subsequent statement released by organisers.
“The doctors have advised me that I need to rest to ensure the injury is not further aggravated and become more serious.”
One player who does appear set to play in Hong Kong is China’s Wang Qiang, who is in the form of her life.
