USC's football team will bolster its depleted defensive line this season with the summer addition of Stevie Tu'ikolovatu, a graduate transfer from Utah, a Pac-12 South Division rival.
Tu'ikolovatu (6-foot-1, 320 pounds) had 28 tackles as the backup for first-team All-Pac-12 tackle Lowell Lotulelei last year, including six tackles for a loss and two sacks.
Defensive tackle is the Trojans' biggest question this fall after losing all three starters on its defensive line, as well as losing junior tackle Kenny Bigelow to season-ending knee injury. USC plays at Utah in its fourth game on Sept. 23.
It opens against Alabama on Sept. 3 at AT&T Stadium.
