The English Football League (EFL) have condemned the "unsavoury and unacceptable incidents" taking place at football stadiums.
In a strongly-worded statement, the EFL reminded supporters of the safety threat that pitch invasions can have, as well as reiterating that it is a criminal offence to enter the playing surface at any time, and consequences include bans as well as a criminal record.
The statement comes after Sheffield United captain - and former Reds striker - Billy Sharp was allegedly "assaulted" by a Nottingham Forest fan after the second-leg of the Championship play-off semi-final clash at the City Ground, a tie settled in Forest's favour after a penalty shoot-out. Nottinghamshire Police have said a man was arrested “after a footballer was assaulted on the pitch” at the end of Tuesday night’s game.

An investigation has been launched, and Chief Inspector Paul Hennessy of Nottinghamshire Police said: "A 31-year-old man has been arrested on suspicion of assault in connection with this incident. He remains in custody and will be questioned by officers.
"Our enquiries into the circumstances surrounding the incident are ongoing. We have spoken to the player concerned and we are working with both clubs who are supporting us with our investigation."
The EFL have since issued a statement addressing a "number of unsavoury and unacceptable incidents take place with supporters entering the field of play".
The statement says: "Unfortunately, at recent end-of season and play-off semi-final fixtures we have witnessed a number of unsavoury and unacceptable incidents take place with supporters entering the field of play.
"These are currently under investigation by the relevant authorities, and the EFL condemns in the strongest possible terms the reckless actions of individuals who have brought the game into disrepute with this unacceptable behaviour. The league is working closely with the police and clubs, offering its full support to the ongoing investigations.
"Supporters are reminded that it is against the law to enter the pitch at any time and could result in a club ban and criminal record. More importantly it puts the safety of players, coaches, managers and match officials at risk. It is vital that those playing the game can do so safe in the knowledge that they will not be subjected to violent, threatening or anti-social behaviour going forward.
"Many people have already lost the privilege of watching their team via club bans this season and further punitive action will follow for those who continue to disregard ground regulations and break the law at football matches.
"We recognise that this lawlessness is being conducted by a small minority of individuals and that the majority of people attending matches are a credit to their club. However, it is not acceptable for supporters to enter the field of play at any time given the EFL’s objective is to ensure our matches remain a safe and welcoming one for all. Therefore, over the summer we will consider what further measures are now at our disposal, including the potential use of capacity reductions or other similar mitigations.
"Fans are also advised that the use of pyrotechnic devices inside a football stadium is a criminal offence that will potentially lead to police action, prosecution, and a ban from football.
"Pyrotechnics and flares can burn at up to 2,500°C and can cause significant injuries to carriers and fellow spectators. We have also seen many incidents that have resulted in people experiencing burns, breathing difficulties, distress, and discomfort.
"Whilst the issue of pitch incursions and the use of pyrotechnic devices are primarily matters that fall within the remit of the police and Football Association, the EFL continues to work closely and collaboratively with all the relevant parties to address the broader issue of anti-social behaviour."
