She failed to complete the first round due to a repeated wrist problem.
Who, who had undergone surgery during the injury in October, said that an MRI scan on Thursday showed "nerve involvement"
"I made the decision to withdraw 15 because I was not able to cancel the club at the time, "said the 29-year-old.
"After surgery I got the idea that I was going to be completely free of pain when I went back to Asia to defend my title.
" I was so ready to be pain free, I ignored a few warning signs. As a result of not listening to my body, I had a bad flare during my round.
"Because I was in so much pain, I was afraid that I could do more damage.
" The decision to withdraw during the tournament is always the most difficult decision, but it was heartbreaking. "
