As the 2021/2022 season draws to a close and the battle against relegation and for promotion intensifies, anti-social behavior among fans have been on the rise.
There were two separate pitch invasions on Thursday night at Goodison Park when Everton beat Crystal Palace 3-2 to maintain their top flight status.
Home fans thronged onto the pitch after Everton's winner and again at full time, with one fan getting into an altercation with Palace manager Patrick Vieira.
On Friday, a fan who headbutted Sheffield United striker Billy Sharp during a pitch invasion on Tuesday when the Blades lost to Nottingham Forest in the championship play-off semi-finals was jailed.
There have also been incidents this week in League Two involving Swindon Town players and Port Vale fans, leaving the football authorities concerned.
"We are very concerned about the rise in anti-social behaviour from fans as we reach the end of the season," a statement from the FA began.
"Football stadiums should always be a safe and enjoyable space for everyone, and these incidents are completely unacceptable and have no place in our game.
"It is illegal to enter the pitch area in any stadium and these actions are putting players, fans and people who run the game at great risk. This simply cannot continue, and we can confirm that we are investigating all of the incidences.
"Clubs play a vital role in addressing this issue and they need to prevent pitch invasions from occurring, as well as taking their own action against those that break the rules and the law.
"The FA will be seeking to do all that it can to work with clubs as well as addressing the issues from a disciplinary perspective. We are also reviewing our regulations to help stamp this behaviour out and to ensure the safety of everyone inside a stadium."
