I was in South Carolina over the weekend to see the Gamecocks take on Tennessee, and the biggest story coming out of the game –from a scouting standpoint or otherwise – is the gruesome knee injury suffered by South Carolina RB Marcus Lattimore (Grade: 88).

The severe hyperextension of Lattimore's right knee is one of the ugliest injuries I've ever seen, and it immediately sucked the energy from the entire stadium. Players from both teams poured onto the field to console Lattimore, who tore the ACL in his left knee last season and reportedly suffered a dislocation of the knee and accompanying ligament damage against the Volunteers.

Before going down Lattimore looked more explosive than he had all season, but his football future now appears to be in jeopardy. Whether he plays again or not, Lattimore's injury also weakens an already-thin running back class for the 2013 NFL draft.
