In what could be one of the last annual matchups between Notre Dame and USC, the Trojans could be out one of their best offensive lineman in Killian O'Connor.
In the second quarter of USC's last game against Illinois, the team's starting center was seen down on the field. It appeared to be his left knee, and he was visibly in pain as the refs called an injury timeout. Although O'Connor was able to walk off the field, as the team entered the second half, O'Connor wore a knee brace and used crutches as the game went on.
