World number two Kim Clijsters is a doubt for Wimbledon after re-injuring her ankle at the Unicef Open.
Clijsters, who recently missed two months with an ankle problem, stumbled in her 7-6 6-3 round two loss to Romina Oprandi but did not have treatment.
“I took some medication on the court that helped with pain in my knee but not my ankle,” she said afterwards.
When asked if it would affect her playing at Wimbledon, she said “it depends on results from the hospital”.
World number 82 Oprandi admitted she was amazed by her victory, but was aware that her opponent was not playing at full capacity.
“There is no bigger thing in tennis, it was a miracle,” she said.
“I think maybe she was not 100% and I tried drop shots. It came out good for me.”
Australian Open champion Clijsters, 28, originally injured her ankle dancing at her cousin’s wedding in April.
After some time out to allow it to heal, she wore strapping on the injury when she competed at the French Open, where she made a second-round exit.
Her second early exit in consecutive tournaments leaves her short of practice for Wimbledon, a tournament which the four-time Grand Slam winner has never won.
It comes on the same day that reigning Wimbledon champion Serena Williams made a winning return to action at the Aegon International in Eastbourne, after a year out because of serious injury and illness.
