In an unfortunate turn of events, Canadian women’s professional tennis star Eugenie Bouchard was forced to withdraw from the US Open Sunday before her scheduled fourth round match against Italy’s Roberta Vinci due to a concussion, per a statement released by tournament director David Brewer.

The 25th-seeded 21-year-old, who reached a career-high No. 5 world ranking last October but has struggled to recapture that level of performance so far in 2015, suffered the head injury Friday night when she slipped and fell in the locker room. Earlier in the day, the 2014 Wimbledon finalist, who had been playing some of the best tennis of her season this week in New York, followed up a three-set, third-round win over Slovakia’s Dominika Cibulkova with a match tiebreak victory in the first round of the mixed doubles competition alongside Australia’s Nick Kyrgios. Friday’s win over Cibulkova marked the first time this year that Bouchard had strung together three consecutive singles match wins. She was also the only woman who remained in all three draws.

Bouchard’s withdrawal on Saturday from her women’s doubles match with partner Elena Vesnina and the highly anticipated mixed doubles match with Kyrgios against Martina Hingis and Leander Paes, resulted in speculation regarding her status for Sunday’s singles match. Sources report that Bouchard wanted to wait as long as possible before making her final decision but it was ultimately determined she was in no shape to play a competitive tennis match. According to several news reports, Bouchard’s symptoms include a headache and sore neck and sensitivity to light and loud noises.

Fellow players have already sent words of support to Bouchard via Twitter; Bouchard did not speak with reporters Sunday and has yet to release a statement on her own Twitter page. With the walkover, Vinci advances to play the winner of Sunday night’s fourth round match between No. 13-seeded Ekaterina Makarova of Russia and France’s Kristina Mladenovic.
