The league had a major potential problem on its hands, under the prior COVID-19 protocol that required daily testing of unvaccinated players. The league has solved that problem, in one simple memo.
With unvaccinated Packers quarterback Aaron Rodgers due to see his 90-day testing holiday expire two days after the NFC Championship, he would have been subject to daily testing from Tuesday, February 1 through Sunday, February 13. With current COVID protocols resulting in a minimum absence of five days for unvaccinated players who test positive, a positive result for Rodgers at any point from Wednesday, February 9 through Sunday, February 13 would have resulted in Rodgers missing the Super Bowl, no exceptions and no questions asked.
