One reason the Big Ten may now feel more comfortable with fall football is advanced COVID-19 tests.

Chicago Tribune sportswriter Teddy Greenstein shared an interesting tidbit from Northwestern Director of Sports Medicine Jeff Mjaanes: Big Ten teams will be able to isolate players before they are contagious by detecting COVID-19 before they become infectious with daily antigen tests.

Early isolation will be important for Big Ten teams to be able to play a full season. The conference has revealed that a 5 percent infection rate will be the threshold for teams to shut down football activities and that players who test positive will be in a 21-day quarantine.
