The Steelers were originally supposed to play the Ravens on Thanksgiving day, but positive COVID tests resulted in the game being pushed to the following Sunday, which was then pushed to Tuesday.
It finally made the move to Wednesday.
The reason for the Sunday Night Football game between the Pittsburgh Steelers and the Baltimore Ravens airing on a Wednesday and therefore confusing viewers is a little bit complicated, so I think NFL fans can be excused for not knowing what exactly was going on.
