USC defensive back Josh Pinkard will miss the season with a torn ligament in his left knee, the school said Tuesday.
Pinkard's injury will require surgery. Pinkard suffered a right knee injury last season.
Pinkard, a junior, had emerged as a starting cornerback after playing safety last season.
Pinkard plans to petition for a sixth season and if granted would have two years to play.
