[U.S. WOMEN] Two-time gold-medalist Lindsay Tarpley is sidelined after tearing the anterior cruciate ligament in her right knee during training with WPS's Chicago Red Stars last week. She joins a group of nine current U.S. pool players who have suffered ACL injuries. Surgeries generally require 8-10 months for a full recovery.

The former University of North Carolina star suffered the injury during the last five minutes of the team's final training of 2009 before facing St. Louis Athletica last Wednesday.

The 25-year-old Tarpley, who has played 119 matches and scored 30 goals for the USA, has not set a date for surgery, but will likely have the procedure within the next two weeks.

She had seen action in six out of the seven matches the USA played in 2009.

A broken leg suffered in 2004 forced her to miss half of her junior and senior seasons at UNC.
