Notre Dame's defense had a lot of hits in a dominating win over Michigan State.
The Fighting Irish, though, had a setback on that side of the ball during their first victory over a top-10 team since 2005.
Starting safety Jamoris Slaughter will miss the rest of the season after tearing his left Achilles tendon in a 20-3 win over the Spartans on Saturday night. The senior started the first three games this year and 19 in his career in which he also played cornerback and linebacker.
Sophomore Matthias Farley is expected to start in Slaughter's place when No. 11 Notre Dame (3-0) hosts No. 18 Michigan (2-1) on Saturday night.
''You lose a Jamoris Slaughter, you're losing an A player,'' Irish coach Brian Kelly said Sunday. ''Matthias is certainly not at the level yet of a Jamoris Slaughter. He's got to continue to develop, but we have a lot of confidence and trust in him. He'll be getting a lot of work back there.''
