Canada's Aleksandra Wozniak has been sidelined for the rest of the year with a joint sprain in her right shoulder.
The country's top female player from Blainville, Que., was diagnosed with an acromioclavicular joint sprain and will be out of action for at least six weeks, ending her 2012 season.
"I am keeping a positive attitude in spite of this new injury I suffered recently at the tournament in Quebec City," Wozniak said in a statement. "I was in a good position heading into the last events of the season because I didn't have a lot of points to defend. It's unfortunate as I was hoping to improve my ranking (No. 43), but I will come back stronger."
Wozniak will undergo physiotherapy as soon as the inflammation and pain subsides, and then begin training for the 2013 season.
She expects to open the WTA season in Australia in January.
