As expected, the NFL confirmed that the Patriots game would be contested on Sunday, rather than Saturday, even before the Texans-Steelers game started.
The NFL has never had a Monday night Wild Card winner play the following Saturday since adding the Monday night game in 2021, and it made things easy in terms of Houston knowing where and when they'd play next week with a win, even before the game started.
Just take a look at the first four years of the playoffs since the NFL took one of the three Saturday games and moved it to Monday.
