World numberone Naomi Osaka has pulled out of next week Qatar Open.
It was first scheduled to be the Japanese’s very first championship since triumphing in the Australian Open in January to win back-to-back Grand Slam titles.
“I am likely to have to draw from Doha in 2013 since I was anticipating playing and watching my fans there,” that the 21-year-old said in an announcement.
“I wish every one a great week and hope to see everyone .”
Osaka has suffered with a back injury, missing October’s Hong Kong Open with the problem.
