The 25-year-old, who clinched the silver medal at the World Championship and regained her World No 1 status last month, did not send her entry for the USD 600,000 tournament, while Jwala has decided to give the event a miss as she is suffering from fever.
"Hit by viral fever cold cough... Most horrible feeling ever..Will be pulling out of Korean open too..Hope to get back ASAP!!" Jwala wrote on her twitter handle today.
