USC Athletic Director Lynn Swann has immediately resigned, according to a letter sent to the USC community by President Carol Folt on Monday.

“Lynn has been a leader on and off the field at USC for nearly five decades, and he will forever be a valued member of the Trojan family,” Folt wrote in a letter to the USC community.

Swann spent three years as the athletic director for USC. During his tenure, USC won five national championships.

He was hired in April 2016 to replace Pat Haden. Swann’s resignation comes months after the nationwide college admission scandals which rocked college athletic departments across the nation. USC is one of several universities accused of accepting bribes to falsely recruit and admit students. After the scandal broke, Swann reaffirmed his commitment to USC.

“I have not considered resigning. I’m committed to this school and I’m committed to this job,” Swann said in an interview with the LA Times earlier this year.

Folt’s special advisor Dave Roberts will serve as the interim athletic director, according to the letter. He came to USC in the summer of 2010 as the vice president of athletics compliance. Roberts also currently serves as the NCAA’s Vice Chair of the Committee on Infractions.

The university also announced the search committee for the next athletic director in the letter. The team consists of USC Trustee Suzanne Nora Johnson as the chair, alumni representative Bill Allen; Vice President for Student Affairs Winston Crisp; Faculty Athletics Representative Alan Green; Academic Senate President Rebecca Lonergan; Provost Charles Zukoski; and trustees Jeff Smulyan, William McMorrow, and Board Chair Rick Caruso.

Swann is the latest in a string of several high profile officials and administrators to leave the university this past year, following former Provost Michael Quick and Senior Vice President for Legal Affairs and Professionalism Carol Mauch Amir.

“Our Athletics Department puts our student-athletes first by pursuing excellence with integrity,” Folt said in her letter. “We will build on the traditions and strengths of our exceptional athletics program.”
