The Monday Night Football games are portrayed as being played in New York, with the Giants as the home team. However, game footage clearly shows the games being played in Philadelphia and Dallas. It would also be unlikely that the Giants would play back to back Monday Night games, and in addition, Monday Night Football would not broadcast any games played in New York until 1979 after NFL Blackout rules were changed.
As the play-by-play is announced, the Cowboys offensive play begins at the Giants 37 yard line, and after the successful, completed pass they end up at the Giants 49, which means they lost 12 yards on the play.
