Notre Dame announced a one-year suspension for its men’s swimming team Thursday after an external review found chronic violations of NCAA gambling rules and issues with the team’s “culture.”

“The external review confirmed and expanded on our initial concerns about a deeply embedded team culture dismissive of Notre Dame’s standards for student-athletes, including our expectation that they treat one another with dignity and respect,” athletic director Pete Bevacqua said in a statement. “We hope this decision sends a clear and unequivocal message reaffirming that commitment and expectation.”
