USC added to its defensive front on Sunday.

Former Purdue edge rusher Jack Sullivan announced on Twitter he has committed to the Trojans. Sullivan will arrive in Los Angeles after five seasons spent with the Boilermakers, giving him just one more year of college ball. A 6-foot-5, 275-pound edge rusher, Sullivan figures to give USC some help at rush end.

A Plainfield, Illinois native, Sullivan played in all 14 games for the Boilermakers with 38 tackles, seven tackles for a loss, and a team-leading 5.5 sacks. Overall, he had 38 total quarterback pressures, the most on the team and the seventh-most among Big Ten defenders.

During his time in West Lafayette, Sullivan appeared in 38 games with 85 total tackles, 13.5 tackles for loss, nine sacks, seven pass breakups, and a forced fumble.

Bolstering the defensive front has been a top priority for the Trojan coaching staff this offseason, and Sullivan is the second transfer lineman to commit to USC. The Trojans are also adding former Arizona defensive lineman Kyon Barrs. USC has also added edge rushers Braylan Shelby and David Peevy from the 2023 signing class, along with three other 3-star defensive linemen.
