Ford Field is one of the few venues in the NFL that has end zones in the east and the west. There is no NFL rule for field construction in roofed venues regarding sunlight distracting players on the field. The east–west end zone design accommodated the Hudson warehouse location. The natural light is not a distraction to the players in a day game, because the light only reaches as far as the sidelines, leaving the field still properly lit with the combination of artificial stadium lighting and sunlight.
