Statement from the NFL; “The Steelers-Titans game, originally scheduled for Sunday at 1 p.m. ET, will be rescheduled to allow additional time for further daily COVID-19 testing and to ensure the health and safety of players, coaches and game day personnel. Details on the new game date and time on either Monday or Tuesday will be announced as soon as possible.”

Titans team will be back in training facility Sunday. This won’t change overall schedule for the league.
Most interesting issue, whether Minnesota Vikings players were infected by Titans players during the game, has not be answered yet.
