The OUE Singapore Open has been hit by a string of late withdrawals on Monday, just a day before the badminton tournament begins.
Men's second seed Kenichi Tago of Japan, and two-time men's singles champion Boonsak Ponsana of Thailand (fourth seed) were the latest to join the list after a team managers' meeting. They join defending men's champion and third seed Tommy Sugiarto, as well as Sony Dwi Kuncoro of Indonesia, both of whom pulled out last week.
This leaves Malaysia's world No. 1 Lee Chong Wei as the only one among the men's top four seeds who will be playing at the Singapore Indoor Stadium.
Reigning world women's singles champion Ratchanok Intanon, however, will still be featuring at the Super Series tournament. China's defending women's singles champion Wang Yihan will also be competing.
Singapore No. 1 Derek Wong will represent the Republic in the men's singles, while Gu Juan will play in the women's singles.
