USC athletic director Lynn Swann has resigned effective immediately, University President Carol Folt announced in an email. Special advisor to the president Dave Roberts will serve as the school's interim AD as a permanent replacement is found.
"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 said.
Roberts currently serves as the NCAA's Vice Chari of the Committee on Infractions. He came to USC in the summer of 2010 as the vice president of athletics compliance.
Four members of the USC athletic's department were implicated earlier this year in a nationwide college admissions cheating, bribery and recruitment scheme, including a senior associate athletic director.
