Canadian tennis player Aleksandra Wozniak is returning after an 11-month injury layoff.

Tennis Canada said Wednesday that Wozniak, the Blainville, Quebec, player once ranked No. 21 in the world, will play a Challenger Series event in Winnipeg, Manitoba, starting Aug. 22. The 27-year-old Wozniak, currently ranked 696th on the WTA Tour, has not played since undergoing surgery on her right shoulder in September.

She reached her career-high ranking in 2009, when she advanced to the fourth round of the French Open, the third round of the U.S. Open and the final of a tournament at Ponte Vedra Beach, where she lost to Caroline Wozniacki. She capped her season by winning the Bobbie Rosenfeld Award, given out by The Canadian Press to the female athlete of the year.

Wozniak won her lone career title in 2008 at Stanford.
