LSU quarterback Zach Mettenberger suffered a torn ACL and an MCL sprain during the Tigers' 31-27 victory last week over Arkansas, multiple sources told ESPN.

The school confirmed Wednesday that Mettenberger will miss the Tigers' bowl game but did not disclose specifics about the injury, per school policy.

"We are very disappointed for Zach," coach Les Miles said Wednesday. "He's been a tremendous leader for our team and he's as competitive a guy as I have ever been around. He's had a great impact on our program."

Mettenberger was hit on his left knee during the fourth quarter by Arkansas defensive tackle Byran Jones. The senior quarterback was wearing a brace on the knee as a precautionary measure, but the force of the blow bent his knee back, causing the damage.

A source said that once the sprain heals -- in an estimated two weeks -- Mettenberger would have surgery to repair his ACL.

Mettenberger, who is known for his arm strength, was thought to be no worse than a mid-first-round pick in the 2014 NFL draft before he suffered the injury, two high-ranking league personnel sources said.
