Notre Dame sophomore safety Drue Tranquill tore the ACL in his right knee and will miss the remainder of the season, Notre Dame coach Brian Kelly announced Sunday. Tranquill is the sixth Irish player to suffer a season-ending injury since the beginning of preseason camp in August.

It's Tranquill's second ACL tear in the last 12 months. The Fort Wayne, Ind. native tore the ACL in his left knee against Louisville last November and underwent surgery that sidelined him for Notre Dame's final two games and spring practice. Tranquill will undergo surgery sometime in the next two weeks and will undergo some rehab before the procedure, Kelly said.

Tranquill was one of Notre Dame's best players in the first half of its 30-22 win over Georgia Tech on Saturday, making four tackles and two tackles for a loss. He broke up a pass in the end zone in the second quarter and, when he went to celebrate with linebacker Joe Schmidt, leaped in the air and landed awkwardly on his leg, which buckled under him. He was seen on the sidelines during the second half on crutches with an immobilizing cast on his right leg.

"Drue Tranquill was a very important player in the back end of our defense because of his versatility," Kelly said.

Notre Dame lost nose guard Jarron Jones (MCL tear) and cornerback Shaun Crawford (ACL tear) during preseason camp. Running back Tarean Folston (torn ACL) was injured against Texas, while quarterback Malik Zaire (fractured ankle) and tight end Durham Smythe (torn MCL) against Virginia.
