 DATE: In the season opener with the Dallas Cowboys, the coin toss is  called "heads" by the Philadelphia Eagles before the coin is tossed  in the air. In 1976 the toss was called while the coin was actually  in the air. The rule of calling the toss before it was actually  tossed by the referee was not changed until after the Thanksgiving  Day game between Pittsburg and Detroit in the 1998 season.
