Zach Mettenberger tore ACL

— -- LSU quarterback Zach Mettenberger suffered a torn ACL during last week's 31-27 victory over Arkansas, multiple sources told ESPN.

Mettenberger was hit on his left knee during the fourth quarter by Arkansas defensive tackle Bryan Jones. The senior quarterback happened to be wearing a brace on his left knee, but the force of the hit bent his knee back, causing the ligament tear. One source said Mettenberger is expected to have surgery on his left knee in about two weeks.

Mettenberger, who is known for his outstanding 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 NFL personnel sources said.

Backup quarterback Anthony Jennings, who took over for Mettenberger against Arkansas and led LSU to victory late in the game, will take over as the starter for the team's bowl appearance.
