Notre Dame senior defensive tackle Rylie Mills will miss the remainder of the postseason with a right knee injury suffered in Friday's College Football Playoff victory over Indiana. The No. 5 seeded Irish will next face No. 2 Georgia in the Sugar Bowl on Jan. 1.

Head coach Marcus Freeman announced Mills' status during his news conference on Monday, lamenting the loss of an impact player and team captain.

Mills was injured while sacking Indiana quarterback Kurtis Rourke in the third quarter. He was replaced by junior Gabriel Rubio.

Following the game, Freeman was told there was optimism the injury wasn't season-ending with 10 days to recover before the Jan. 1 matchup with Georgia. That obviously changed after further examination.

In 13 games this season, Mills compiled 37 combined tackles (19 solo) and led the Irish with 7.5 sacks.

Mills' injury is the latest for a defensive line that lost defensive ends Jordan Botelho and Boubacar Traore earlier this season. Botelho suffered a knee injury in the third game of the year versus Purdue, while Traore was hurt two weeks later against Louisville. Additionally, the Irish lost starting cornerback and captain Benjamin Morrison the following week with a hip injury versus Stanford.

Despite the injuries, Notre Dame finished sixth in the nation in total defense and tied for fifth in scoring defense (allowing 17 points per game) and rushing defense.
