This is one you don’t see very often.

USC’s Josh Fatu was involved in a multi-car accident and is currently in concussion protocol because of a head injury he received in the incident, head coach Clay Helton confirmed Tuesday. The coach added that the accident in which Fatu sustained the injury was not the defensive tackle’s fault.

Fatu has not been ruled out for Saturday’s game against Notre Dame, and is officially listed as day-to-day for the annual rivalry clash.
