Britain's Emma Raducanu has pulled out of an exhibition match in Macau at the start of December as she continues her rehabilitation from hand and foot operations.
The 2021 US Open champion - who turns 21 today - has not played since April, but is still hoping to return to the tour in January.
The exhibition in China has come too soon, however, especially as the organisers wanted time to seek out a potential replacement.
Raducanu has fallen to 289 in the world rankings, but will be able to use a protected ranking of 103 next year as she has not played for over six months.
