Notre Dame president John Jenkins has announced consequences for students who rushed the field after the Fighting Irish’s upset win over Clemson on Saturday.

The university is now even more concerned about the spread of COVID-19. Here’s a letter that university published Monday night:

Notre Dame is insisting that some students remain on campus until they’ve produced a negative test. If they leave prior to knowing the results of their test, they will have an “administrative hold” put on their record and may not be able to return to campus for the spring semester.

That’s going to alter some students’ plans with Thanksgiving approaching and the fall semester ending soon.

There will also be “zero tolerance” for hosting large gatherings on or off campus, per the letter.

Notre Dame defeated Clemson 47-40 and now sits alone in first place in the ACC.
