A greater number of professional football based injuries have been reported when playing on artificial turf surfaces. This study investigated whether artificial turf or natural grass causes more professional football related injuries. Data were collected from a random sample of videotapes of the 1985 National Football League (NFL) season and by performing a literature search of all severe injuries of the 1984 season. There were no significant differences between the amount of severe injuries occurring on artificial and natural grass surfaces. A major cause of football injuries resulting in severe injuries is that football is inherently a violent sport and those same injuries seem to occur against a few teams.
