LSU moved up in both top 25 polls this week after their impressive 33-17 victory over Miami on Sunday night, but the win didn't come without a setback.

Sophomore linebacker K'Lavon Chaisson will miss the remainder of the season after suffering a torn ACL in the 4th quarter. Coach Ed Orgeron confirmed the news today.

"I feel bad for him," noted Orgeron. "He's a great young man. He had totally dedicated himself to this year."

Chaisson, a top 30 recruit on several recruiting websites coming out of high school in Houston, is a top tier edge rusher for the Tigers defense.

He started and played well in Sunday's win, procuring five tackles, one sack, a tackle for loss and one quarterback hurry in his start.

On another injury note for LSU, starting right tackle Adrian Magee will miss the next two to three weeks according to Orgeron. Magee left Sunday's game with an apparent leg injury.
