LSU lost quarterback Zach Mettenberger to an apparent knee injury in the fourth quarter, the senior getting hit around the wait just as he released a long downfield pass. CBS sideline reporter Kristina Akra reported that LSU's trainers were examining Mettenberger's left knee after he had been helped off the field.
Mettenberger was later shown using crutches to move around the Tiger Stadium field in the Tigers' postgame celebration.
Though Mettenberger wears a brace on the left knee, he denied in October that there were any structural problems.
Backup quarterback Anthony Jennings came in and led the Tigers on a 99-yard game-winning drive, throwing the game-winning 49-yard touchdown pass to Travin Dural. That accomplishment was even more impressive given that Jennings was without the services of Odell Beckham Jr., the SEC's third-leading receiver.
The junior wideout -- who came into the game with 1,101 receiving yards, the nation's 19th-best total -- left the game in the first half wit ha reported hip flexor. Though Les Miles did not rule out a return for Beckham in the second half, he did not see the field.
LSU starting offensive linemen Elliott Porter and Jerald Hawkins also left the game with injuries.
