Emma Raducanu says she hopes she will be fit for this month's Australian Open but is trying "not to expect too much".
The Grand Slam begins next Monday, with the full extent of the 2021 US Open champion's injury yet to be diagnosed.
"We'll see hopefully by Monday or whenever the tournament starts," Raducanu said.
"We're just taking it a day at a time and not trying to expect too much at this point."
Raducanu left the court in tears last week after rolling her ankle during the second set against Slovakia's Viktoria Kuzmova, with the score 6-0 5-7.
