 Undaunted, Rozelle decided to experiment with the concept of playing on Monday night, scheduling the Green Bay Packers and Detroit Lions for a game on September 28, 1964.While the game was not televised, it drew a sellout crowd of 59,203 spectators to Tiger Stadium, the largest crowd ever to watch a professional football game in Detroit up to that point.Two years later, Rozelle would build on this success as the NFL began a four-year experiment of playing on Monday night, scheduling one game in prime time on CBS during the 1966 and 1967 seasons, and two contests during each of the next two years.
