USC starter Josh Fatu day-to-day with concussion after auto accident

USC starting defensive tackle Josh Fatu was involved in a multi-car accident and is currently in concussion protocol, coach Clay Helton said Tuesday.

Fatu, who has 27 tackles and seven tackles for loss, will continue to be evaluated and Helton classified his status as "day-to-day." Helton said the accident was not Fatu's fault. If he is unable to play on Saturday against Notre Dame, Brandon Pili would be expected to start in his place.

Helton also announced that another of Fatu's backups, redshirt senior Kenny Bigelow, will transition into a role with the program as a result of recurring knee injuries. Bigelow arrived at USC ranked as the No. 21 player in the ESPN 300 in the Class of 2013, but his career has been mired by injury problems. Helton said Bigelow hopes to one day become a coach and his new role will help prepare him for that.
