Ai Miyazato has withdrawn from the HSBC Women's Champions in Singapore as a precaution after she was hurt in a weekend auto accident.
Miyazato, the 2010 champion, withdrew on Wednesday after hitting balls for about 15 minutes.
The former No. 1-ranked Miyazato issued a statement saying she still had stiffness in her neck, shoulder and back "but it is also a precautionary measure so as not to risk further injury."
The U.S. LPGA Tour said Paula Creamer, Suzann Pettersen and Miyazato were involved in a five-vehicle crash in Thailand on Sunday.
Creamer told a pre-tournament news conference she had "pretty bad whiplash from hitting the headrest but I took it easy and I hope that I can tee it up" when the tournament starts on Thursday.
