Notre Dame pass rusher Boubacar Traore will miss the rest of the season with a torn left anterior cruciate ligament, coach Marcus Freeman announced Monday.

Freeman said that Traore sustained the injury during the Fighting Irish’s 31-24 home win over then-No. 15 Louisville on Sept. 28. Notre Dame had a bye last week.

Traore led the Irish with three sacks and five tackles for loss across five games this season. The redshirt freshman has tallied 12 tackles — six for loss — with four sacks, two forced fumbles and an interception in 10 career games (two starts) for Notre Dame.

Junior Tuihalamaka is expected to replace Traore at the viper position, a blend of defensive end and outside linebacker. Tuihalamaka, a junior, has seven tackles — 1.5 for loss — with a half-sack and an interception in five games (no starts) this season.

The 11th-ranked Irish (4-1) host Stanford (2-3) on Saturday.
