The English football league system does not include the amateur version of the game often called Sunday league football. These leagues are independent. They do not have promotion or relegation. They do not belong to the football pyramid. However, some Sunday league clubs sometimes join pyramid leagues. This is often if they want to play at a higher level. There are also some Saturday leagues which are not officially part of the pyramid. However, teams often leave these for pyramid leagues. The FA accepted a non-promoting Saturday league (a league with no promotion or relegation) to the pyramid in May 2017. This was the Lincolnshire League.
