Baltimore Ravens President Dick Cass on Wednesday broke down the team's rigid procedures meant to keep the coronavirus out.
Cass told C4 and Peter Schmuck that their procedures, informed by league and union guidance, include the use of employee tiers and proximity trackers.
"It's a very rigorous program. It's a carefully negotiated protocol," Cass said. "There's a lot of education that comes along with it, educating both the staff and players and families."
Trackers, which every team employee has to have on their person, link to a computer system and log every other team employee the person has come near.
