Picture of the day: Georges St. Pierre begins knee rehab

The UFC welterweight champ tore his ACL when training for a bout with Nick Diaz. While the UFC moves forward with an interim belt, George St. Pierre is at the beginning of a long road back to having a healthy leg again.
That started with surgery, which was deemed a success, and now rehabilitation. Above, he is in a continuous passive motion machine, which prevents GSP's leg from getting stiff without putting him in pain.
