Notre Dame will finish the season without nose guard Louis Nix III.
Coach Brian Kelly told reporters Thursday that the 6-foot-2, 357-pound senior underwent season-ending knee surgery to repair a meniscus. Notre Dame (7-3) plays host to BYU (7-3) on Saturday before finishing the season at No. 10 Stanford (8-2) on Nov. 30
Nix recently told reporters he had been battling knee tendinitis since the Irish's 42-14 loss to Alabama in the BCS championship game Jan. 7.
Nix missed Notre Dame's 45-10 win over Air Force on Oct. 26 and 38-34 win over Navy on Nov. 2 because of the tendinitis. He returned for the Irish's 28-21 loss to Pittsburgh on Nov. 9, but Kelly revealed that the lineman had also been dealing with a torn meniscus before that game.
Nix was expected to be able to battled through the injury in the final two games, but that changed with the surgery. Nix had 27 tackles, with two for loss, in eight games this season.
Kelly said Nix will be able to walk on the field for Senior Day on Saturday. And that may be the last thing Nix does in Notre Dame Stadium.
Nix has the option to return for a fifth year to Notre Dame after not playing as a freshman, but he is projected to be a first-round pick in the NFL draft.
