‘The Bills’ rookies now will wait over the next two days at their homes or hotels – Wednesday and Thursday – and self-quarantine, under protocols agreed upon Monday. They will return to the Orchard Park facility Friday for another Covid-19 test. The idea is that 72-hour window between tests allows teams to more likely catch the virus if it was incubating and the player had a negative first test. Virtual meetings can be held on the days between the two tests. Players and staff who test negative on the second test then may enter team facilities for the first time. At that point, daily Covid-19 testing begins.’
