Notre Dame's 20-3 victory over Michigan State on Saturday night came with a price.
Irish coach Brian Kelly said on his teleconference Sunday that safety Jamoris Slaughter suffered an Achilles tendon injury against the Spartans and will miss the rest of the season.
Slaughter, a 6-foot, 200-pound fifth-year senior, will have surgery this week and his college career could be over.
Slaughter had eight tackles this season, and he started 19 of 39 games in his career, compiling 98 tackles, four for loss, two interceptions and six pass breakups.
With Slaughter out, Notre Dame will likely turn to sophomore Matthias Farley to start next to senior Zeke Motta at safety when the No. 11 Irish (3-0) play host to No. 18 Michigan (2-1) on Saturday.
Freshmen Elijah Shumate and Nicky Baratti will also likely have their playing time increased.
"You lose a Jamoris Slaughter, you're losing an 'A' player," Kelly said. "Matthias is certainly not at the level yet of a Jamoris Slaughter. He has 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."
Slaughter's injury is a third blow to the Irish's secondary this season. Notre Dame also lost cornerback Lo Wood, who was expected to start, to an Achilles injury during fall camp, and safety Austin Collinsworth was lost for the year after shoulder surgery during the off-season.
Wood's injury forced the Irish to use two first-time starters at corner with junior Bennett Jackson and freshman KeiVarae Russell.
Kelly said he isn't concerned about having three-quarters of his secondary being inexperienced.
"You're worried if you feel have to hide them out there," Kelly said. "We don't have to hide those guys. They just need to continue to develop."
Kelly also provided updates on some other players with injuries during his Sunday teleconference.
Kelly said receiver DaVaris Daniels, who was nursing a sprained ankle, suffered a setback on Friday and was limited against Michigan State. Kelly said he hopes Daniels will be "full go" this week.
Defensive end Kapron Lewis-Moore is still not 100 percent after suffering a calf injury against Purdue, but Kelly said the senior is raising his ability to play through injury.
"I think in his own mind he's reaching new levels as to what he can do and fighting through this calf injury," Kelly said. "He's better today than he was when he started the game. We think that's a really good sign. We think we'll get him close to a hundred percent this week."
Kelly also said defensive end Sheldon Day suffered a bone bruise against Michigan State, but the freshman should be fine.
