QUEBEC — Eugenie Bouchard withdrew from the National Bank Cup on Friday due to a virus.
The Westmount, Que., native was a semifinalist at the tournament in 2013.
Bouchard, ranked No. 76 in the WTA rankings, was coming off a first round exit at the U.S. Open against Russia’s Evgeniya Rodina. It dropped her record to 12-17 this season.
"I have been dealing with a virus for the past few days that has not allowed me to train since the end of the U.S. Open and will prevent me from playing the tournament," Bouchard said in a statement. "I will focus my energy on recovering, but I don’t know when I will be able to return to competition."
The 23-year-old Bouchard has failed to make it past the second round in her last eight tournaments.
Bouchard will be replaced in the main draw by Marina Erakovic of New Zealand.
Oceane Dodin of France is the defending tournament champion.
