LONDON -- Canada's Bianca Andreescu has dropped out of Wimbledon because of an ongoing shoulder injury.

The 19-year-old from Mississauga, Ont., Canada's top-ranked women's player at No. 25, withdrew from the French Open last month after winning her first match because of the right shoulder problem.

Andreescu suffered the injury in March. She pulled out of a fourth-round match at the Miami Open due to a subscapularis muscle tear in the rotator cuff of her right shoulder.

The injury came after an excellent start to the season for Andreescu, highlighted by an improbable run to the BNP Paribas Open title in Indian Wells, Calif., in March.

Andreescu's withdrawal leaves Eugenie Bouchard of Westmount, Que., as the only Canadian in the women's singles main draw, which starts July 1.

Tennis Canada is hoping Andreescu is ready for the summer hard-court season. It has been promoting Andreescu as the Tuesday night headliner for the Rogers Cup in Toronto on Aug. 6.
