Yes, the last 0-0 game in the NFL was in 1943 between the Lions and the Giants.
The score of a forfeited NFL game is 2-0. The reasoning behind this is that a safety is the only way to score in an NFL game in which no points are credited to a specific player. There has only been 1 official forfeit in NFL history (1920 - Rochester Jeffersons lost by forfeit to the Washington Pros/Senators).
73-0 in 1940
