Notre Dame quarterback Riley Leonard underwent a second surgery for an ankle injury, per On3 Sports' Tyler Horka.
Leonard, who transferred to Notre Dame after three seasons at Duke, originally suffered the injury last September while playing for the Blue Devils. He aggravated the injury again a few weeks later.
There's no timetable for his return for now, but Notre Dame head coach Marcus Freeman said the surgery went "extremely well."
"Riley Leonard will be out a few weeks due to an additional surgery he had on his ankle on Friday to address a stress fracture that was beginning to develop," Freeman said.
