Southern California defensive lineman Kenny Bigelow is out for the season after tearing his right ACL during non-contact drills in a voluntary workout.

The redshirt freshman was expected to compete for a starting spot. He redshirted last year to adjust to the college ranks. Returning starters Leonard Williams and Antwaun Woods will anchor the defensive line, but the third spot remains open.

Bigelow's injury was announced on the school's blog.
