A former USC football player is taking the school to court over a head injury.  Ex-cornerback Brian Baucham is suing USC and former head football coach Lane Kiffin, saying he was forced to play with a concussion and suffered a brain injury as a result.  He says the medical staff has told him he shouldn't take the field, but that Kiffin ordered him to play in a game against Cal in the fall of 2012.  USC isn't commenting on the lawsuit.
