Michigan State University is hitting the pause button on team workouts after a staff member tested positive for COVID-19. The school released a statement late Wednesday evening.

Last week, Michigan State announced that three student-athletes tested positive in its most recent round of testing. There was also one staff member who tested positive for the virus, the first the school had reported.

COVID-19 tests were conducted on all staff members over the weekend and a staff member had a positive result. Out of caution, the school has decided to halt workouts temporarily.

“As Michigan State football prepared for the beginning of the 20-hour week, during which student-athletes and staff would be in larger groups than they had been during voluntary workouts or the eight-hour weeks, it conducted surveillance COVID-19 testing on all staff member over the weekend, and previously scheduled surveillance COVID-19 testing on the student-athletes Wednesday afternoon,” the school said. “Late Wednesday afternoon, after testing on student-athletes had been completed, one staff member received a positive result. Michigan State football will pause workouts and will not begin its 20-hour weeks until it receives the complete results from all surveillance testing.”

Last week, Michigan State reported that it had conducted a total of 506 COVID-19 screening and had received just eight positive results.
