LOS ANGELES (AP) Southern California athletic director Lynn Swann resigned Monday after three tumultuous years on the job at his alma mater.

New USC President Carol Folt announced the decision in a letter expressing her "sincere appreciation" for the former Trojans receiver.

"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.
