It appears the league's only plan was to expand the practice squad and make it easier to move players from the practice squad to the active roster, and also to place less restrictions on the injured list.
They have protocols right down to the coin toss and national anthem, but no mention of what to do if eight players test positive.
I don't see how they could reschedule any game, unless those two teams have the same bye week.
