Marcus Lattimore was looking to bounce back from the left knee injury he suffered last year, where he needed surgery to repair 6 torn ligaments and cartilage. That injury took him six months to recover. Prior to that, he was one of the best backs in the country and would've been drafted high had he came out. Sadly, the injury today might end his career. During the second quarter of their game vs. Tennessee, one Volunteer defender hit him high and another one hit him low, completely separating his right knee causing it to do a helicopter motion in the air before it flopped onto the turf.

Marcus Lattimore rushed for 597 yards and 10 touchdowns this season.
