The NFL has been using natural grass as a playing surface since the beginning of the sport. In 1966, the first artificial turf was established by the Houston Astros, a Major League Baseball franchise. It was later rebranded as AstroTurf.In 1969, the University of Pennsylvania moved to artificial turf for its Franklin Field. The playing area was also used by the Philadelphia Eagles at the time, making it the first AstroTurf surface in the NFL. It was later changed to Bermuda grass.Initially, the new turf seemed green and convenient to play football on. However, professionals started suffering knee and leg injuries due to increased traction. Yet, due to advancements in turf technology, the NFL allows the use of AstroTurf to conduct regular league games.As of 2022, 14 franchises are using artificial playing surfaces.
