However, we won’t see until Week 7 what this signing has wrought. Even if Bell was 100 percent ready for Monday on short notice, the NFL’s Covid-19 testing protocol for new roster additions will keep him sidelined. Last week following the Tennessee Titans Covid-19 outbreak, the NFL beefed up the various protocols, including when signed free agents can join a team, per the Washington Post. A free agent is not allowed to enter a team’s facility until Day 6 after their initial arrival. They must have negative Covid-19 tests for five straight days and a point-of-care test on Day 6 before they will be allowed entry.
