Regarding the games, it seems like the most likely outcome is proceed with week 18 as scheduled, and once that's concluded, consider if the Bills-Bengals is even necessary (which it probably will be but there may be some scenario where the seeding is solidified), then possibly reschedule it for next Thursday, and push back by a day or two any resulting wild card games that either are involved in. Or have the Bills-Bengals play either 1/14 or 1/15 and push the playoffs back one week (which would condense the Super Bowl wait from two weeks to one).
