The NFL adopted free substitution, April 7. The league also made the wearing of helmets mandatory and approved a 10-game schedule for all teams.
Philadelphia and Pittsburgh were granted permission to merge for one season, June 19. The team, known as Phil-Pitt (and called the Steagles by fans), divided home games between the two cities, and Earle (Greasy) Neale of Philadelphia and Walt Kiesling of Pittsburgh served as co-coaches. The merger automatically dissolved the last day of the season, December 5.
