Northwestern has now become the sixth B1G program to halt football workouts since student-athletes have been permitted to return to campus. The school’s athletic department sent out a statement on Monday.

Teddy Greenstein of the Chicago Tribune was the first to report the news.

According to a release from the school, Northwestern is temporarily pausing football workouts after receiving a positive result from a COVID-19 test. All workouts will be halted until Wednesday at the earliest.

The school will work through contact tracing protocols with those who may have come into close contact with the individual who tested positive.

“Northwestern football has paused workouts, out of an abundance of caution, following a positive COVID-19 test result,” the school said in a statement. “During this time medical staff will implement the University’s rigorous contact tracing and quarantine protocols to protect the health and safety of student-athletes, coaches and staff.”

The other five B1G programs to pause workouts this summer have been Indiana, Maryland, Michigan State, Ohio State and Rutgers. Two programs — Michigan State and Rutgers — have forced their entire football teams to quarantine due to positive test results.
