Chargers RE Corey Liuget exited Thursday night's preseason game against the Bears with a shoulder injury and will not return. Liuget made his presence felt in the quarter of action he played, racking up two tackles for loss and a sack. The Union-Tribune San Diego identified Liuget as a breakout candidate earlier this summer. Hopefully for the Chargers, it doesn't prove to be anything serious. He's a key component on defense.
