Emma Raducanu plays a shot
Raducanu is ranked 78th in the world

The chances of British number one Emma Raducanu playing in the Australian Open are unknown.

The full extent of the problem is not yet known, but the hope is that it is a small problem.

The first Grand Slam of the year takes place in January.

The US Open champion did not enter any tournaments.

She won her first match in New Zealand in preparation for the first major of the year.

The world number 78 left the court in tears after rolling her ankle in the second set of her match against the Slovakian. She didn't like the courts.

In December, she said she was feeling good, even though she had retired from five matches.

She lost to Danka Kovinic in the second round of the Australian Open.
