Aston Villa midfielder Jack Grealish was attacked by a spectator who ran on to the pitch in the Championship match at rivals Birmingham City on Sunday.
It happened in the 10th minute when a man wearing a cap came on to the pitch from the home section before swinging his arm towards Grealish’s face.
The man, who was wearing a Birmingham City jacket, blew kisses towards the crowd as he was led away by stewards.
West Midlands Police said a man has been arrested following the incident.
Villa captain Grealish sat on the St Andrew’s turf before being helped up by players from both teams and was able to continue.
The EFL issued a statement saying it condemned the man’s actions, adding:
“It’s a situation no player should ever be faced with.
“Those playing in the game must be able to do so safe in the knowledge they will not be subjected to this type of behaviour.
“While this incident falls within the remit of the Football Association, we will work with all the relevant parties to address the issue of player and match officials’ safety on the pitch and ensure the appropriate action is taken.”
