University of South Carolina running back Marcus Lattimore suffered a HORRIBLE knee injury on Saturday, where his leg actually bent BACKWARDS. The official word is he dislocated it, and also suffered ligament damage.

His coaches said they're hopeful he'll be able to return either next year or in 2014.  But it's also possible that he'll never play again.

It happens at about :10, you see it twisted at :20, and in slow motion at :60, and again at 2:30.

In other injury news, a 19-year-old football player in Florida was making a tape to send to college recruiters, and tried to jump over a CAR that was speeding toward him. Unfortunately, he jumped late and not NEARLY high enough.  He reportedly broke one of his arms and one of his legs.  The video is up on YouTube.
