No. 4 Notre Dame is looking to shore up its defense when it hosts struggling Louisville on Saturday. The Fighting Irish allowed 405 yards in their last game against Florida State, and coach Brian Kelly knows they'll need to improve on that side of the ball if they want to compete for championships. Louisville has shown the ability to move the ball with running back Javian Hawkins and quarterback Malik Cunningham, but has been hurt by turnovers and sacks.

Why it matters

Notre Dame is aiming for a spot in the College Football Playoff, so improving its defensive performance is crucial. Louisville has the offensive talent to pull off an upset, but has been its own worst enemy with mistakes. This game will be a test of Notre Dame's ability to tighten up on defense against a dangerous opponent.

The details

After not practicing for nine days and not playing for three weeks due to a COVID-19 outbreak, Notre Dame allowed 405 yards in a 42-26 win over Florida State last Saturday. The Fighting Irish will look to get back to the level of defense that defensive coordinator Clark Lea has established. Louisville, meanwhile, has lost three straight games, including a 46-27 defeat at Georgia Tech last Friday, despite outgaining the Yellow Jackets 471-450 and rushing for a season-high 242 yards. The Cardinals have been hurt by 11 turnovers and 14 sacks this season.

  • Notre Dame last played on April 3, a 52-0 win over South Florida.
  • Louisville last played on April 10, a 46-27 loss at Georgia Tech.

What they’re saying

“I think there were some uncharacteristic defensive lapses that we don't normally see. We had a lot of guys that were not practicing during the week and it showed. It's not the kind of defense that Clark (Lea, his defensive coordinator) has put out there nor the kind of defense that I want to put out there.”

— Brian Kelly, Head coach, Notre Dame Fighting Irish

“I think the most glaring thing that stands out is the turnovers. We were able to move the ball most of the night, but if you turn the ball over, you're losing opportunities to go down and get points.”

— Scott Satterfield, Head coach, Louisville Cardinals

What’s next

Notre Dame will look to get back to full strength on defense, while Louisville aims to clean up its turnover issues ahead of the matchup.

The takeaway

This game will be a key test for Notre Dame's championship aspirations, as the Fighting Irish must tighten up on defense to slow down Louisville's dangerous offense. The Cardinals, meanwhile, need to eliminate the mistakes that have plagued them in order to pull off the upset.
