But look at the protocols and threshold for stoppage

The earliest a student-athlete can return to game competition is 21 days following a COVID-19 positive diagnosis.

The Big Ten Conference will use data provided by each Chief Infection Officer (CInO) to make decisions about the continuation of practice and competition, as determined by team positivity rate and population positivity rate, based on a seven-day rolling average:

Team positivity rate (number of positive tests divided by total number of tests administered):
Green 0-2%
Orange 2-5%
Red >5%

Population positivity rate (number of positive individuals divided by total population at risk):
Green 0-3.5%
Orange 3.5-7.5%
Red >7.5%

Decisions to alter or halt practice and competition will be based on the following scenarios:
Green/Green and Green/Orange: Team continues with normal practice and competition.
Orange/Orange and Orange/Red: Team must proceed with caution and enhance COVID-19 prevention (alter practice and meeting schedule, consider viability of continuing with scheduled competition).
Red/Red: Team must stop regular practice and competition for a minimum of seven days and reassess metrics until improved.
