World number two Simona Halep has withdrawn from next week's Aegon Classic in Birmingham due to a right ankle injury, organisers said on Thursday.
Poland's tenth-ranked Agnieszka Radwanska and Monica Puig of Puerto Rico have both pulled out citing illnesses.
Heather Watson, the second-ranked British woman behind world number eight Johanna Konta, has been handed a wildcard along with compatriot Naomi Broady.
World number one Angelique Kerber, two-times Wimbledon champion Petra Kvitova and 2016 WTA Finals champion Dominika Cibulkova will all be in action at the WTA Premier level tournament in Birmingham.
