A teary-eyed Eugenie Bouchard retired from her opening match against Andrea Petkovic at the China Open due to dizziness on Monday, her first match since falling at the US Open last month and suffering a concussion.
Bouchard slipped in the locker room after her third-round win against Dominika Cibulkova at the US Open, falling backward and landing hard on the back of her head. She was forced to withdraw from the tournament, as well as subsequent tournaments in Tokyo and Wuhan.
The Canadian was trailing 6-2, 1-1 against Petkovic on Monday when she decided to call it quits.
"I thought I was physically ready, but unfortunately the symptoms of my concussion came back," Bouchard said in a statement. "I hope to get well soon and look forward to returning next year."
"Then I asked if it was the same, if it still was the concussion. She said, 'Yeah, it tends to come back when she gets physically very active," Petkovic said after the match.
Meanwhile, in women's second-round matches on Monday, US Open runner-up Roberta Vinci of Italy defeated Alison Van Uytvanck of Belgium 6-2, 6-2, Madison Keys of the United States rallied to beat Kateryna Bondarenko of Ukraine 3-6, 6-1, 6-0. In the men's draw, eighth-seeded Jo-Wilfried Tsonga was upset byAndreas Haider-Maurer 7-6 (4), 6-2.
