I think I read that the NFL has postponed 3 games now till Tuesday.
Yes that is correct. As of my previous post, they had not postponed any games.
The Raiders-Browns game moved to Monday evening, while the Seahawks-Rams and the WFT-Eagles games were both moved to Tuesday evening.
The NFL recently changes its protocol too. Vaccinated players can exit the COVID list of they test negative twice in a 24 hour span and are asymptomatic now. I think the idea behind that is to potentially allow more players to return to the roster quickly if they are feeling fine and test negative.
