As Notre Dame opened voluntary workouts in preparation for the upcoming football season came word that one of its players tested positive for COVID-19.

The student-athlete is asymptomatic and self-isolating. After contact-tracing, four other players are in self-quarantine, according to the University.

Of the more than 90 players tested, four tested positive for the COVID-19 antibody.

As many as 50 staffers, including coaches, athletic trainers and student staff have been tested and all were negative.
