Eugenie Bouchard was reduced to tears on Monday after her return from concussion was cut short when she suffered dizziness in the first round of her China Open match against Andrea Petkovic.
The Canadian pulled out of the US Open last month after slipping in the locker room at Flushing Meadows and sustaining a head injury.
Bouchard ruled herself out of the Wuhan Open last week, revealing that she was still suffering from concussion symptoms, but returned to the court to face Andrea Petkovic in Beijing this week.
The 21-year-old was unable to complete the match, though, and sobbed after retiring from the tournament when trailing 6-2 1-1.
Petkovic went over to check on Bouchard as she sat in her chair and revealed that last year’s Wimbledon finalist is still being troubled by the blow she took to the head in New York.
The 13th seed from Germany said: “I just asked her what happened and she told me that she felt very dizzy.
“Then I asked if it was the same, if it was still the concussion. She said it tends to come back when she gets physically very active.
“I feel it’s really bad luck because I thought she was playing so well again.”
