British number one Johanna Konta has withdrawn from the Hong Kong Open because of an abdominal strain.
The world number nine pulled out of the tournament shortly before her second-round match against Wang Qiang.
Konta currently occupies the final qualifying position for the season-ending WTA Finals in Singapore.
But the 25-year-old, the first British woman in the top 10 since 1984, could be overtaken by Dominika Cibulkova if the Slovak makes the Linz Open final.
