COVID-19 means each week B1G fans will be asking, Who's not gonna play? or Will our opponent play? or Will we play? These will be particularly interesting questions before OSU-PSU, The Game and the B1G CG.

Per the B1G:

All COVID-19 positive student-athletes will have to undergo comprehensive cardiac testing to include labs and biomarkers, ECG, Echocardiogram and a Cardiac MRI. Following cardiac evaluation, student-athletes must receive clearance from a cardiologist designated by the university for the primary purpose of cardiac clearance for COVID-19 positive student-athletes. The earliest a student-athlete can return to game competition is 21 days following a COVID-19 positive diagnosis.

What's the B1G's cut-off day for testing?

Fox, ESPN et al would never agree to gameday COVID-19 tests.

So, the cut-off day for testing would be on travel day?
