Michigan State University said a second round of COVID-19 testing on student athletes found two more student-athletes who test positive.
According to MSU, the second round of testing done on Monday doesn't include the other student-athlete who tested positive on June 15.
Those who tested negative twice are able to take part in voluntary workouts, which will be split into small groups based on the people who they live with.
The two student-athletes who tested positive will be isolated for 10-14 days, and another student-athlete who was in close contact with one of the people who tested positive will be required to self quarantine for 14 days.
No athletic department staff member tested positive.
Earlier this month, the university announced protocols for student-athletes coming back to school for voluntary workouts.
Football, men's and women's basketball and volleyball will be the first to return and undergo coronavirus testing.
Anyone entering buildings will go through a single-door and undergo health screenings and temperature checks. Student-athletes will also be required to wear face masks at all times except during workouts. They will also get their own water bottles to use and bring to each workout. Locker rooms will remain closed.
MSU Athletics provided the following statement:
"Michigan State conducted testing for COVID-19 on 124 student-athletes on Monday, June 15. One student-athlete tested positive and will be isolated for a period of 10-14 days. Housing will be arranged based on prior living arrangements and need for isolation if living with others. During this time, daily check-ins with athletic training staff will be conducted, with additional services provided as directed by the medical and administrative staffs. Further testing and physician follow-up will be required prior to returning to any level of workouts.
