Canadian tennis star Eugenie Bouchard has withdrawn from the U.S. Open before her fourth-round match against Italy’s Roberta Vinci. Bouchard, ranked as world no. 24, was dropped from the tournament in New York due to a “head injury” she suffered during a horrific locker room accident on Saturday, Sept. 5.

Bouchard retired from both her women’s doubles and mixed doubles matches that were scheduled on Saturday, Sept. 5, and abandoned her fourth round clash against Vinci. U.S. Open tournament director David Brewer confirmed in a statement that the 21-year-old Canadian withdrew from the competition heading into her last 16 match.

"Eugenie Bouchard is withdrawing from the women's singles competition at the 2015 US Open due to a concussion,” Brewer said.

Bouchard, who had only won nine of 17 matches coming into the final Grand Slam of the year, slipped on a recently cleaned floor in a dark room while getting an ice bath and was taken to hospital afterwards. After the accident, the Canadian international developed several symptoms of a concussion, which include a headache, and sensitivity to noise and light, the National Post reported.

Bouchard was also hoping that she would be able to play despite withdrawing from the ladies and mixed doubles tournaments on Sunday. However, Bouchard could not ignore the symptoms of the injury, ESPN reports.

Bouchard grabbed her third straight win after defeating Slovakian Dominika Cibulkova 7-6(9) 4-6 6-3 in the women’s singles category to reach the fourth round. After her mixed doubles victory with Australia’s Nick Kyrgios, Bouchard said she had been proud to be the only participant still alive in all three categories.

“That was my ultimate goal when I signed up for all three,” Bouchard said. “Very proud of myself for that.”
