Lower than every week earlier than Saban mentioned he had examined optimistic, the SEC’s chancellors and presidents had permitted an replace to the league’s medical protocols. Below the brand new coverage, an asymptomatic individual like Saban who examined optimistic for the virus may take one other P.C.R. take a look at inside 24 hours. If that take a look at yielded a adverse end result, the individual may take two extra P.C.R. assessments, every separated by 24 hours. If all three outcomes had been adverse, the participant, coach or workers member may return to athletics.
