Aston Villa midfielder Jack Grealish was attacked by a spectator early in his side’s derby clash at Birmingham.
The incident occurred less than 10 minutes into the game when Grealish was in the Birmingham penalty area and a spectator in a flat cap ran on to the field and threw a punch from behind the visiting captain, striking him on the side of the head.
The intruder was quickly restrained by stewards as several other Villa players rushed in to confront him. He was led away by police, blowing kisses to the crowd as he left.
West Midlands Police have confirmed the man has been arrested.
An EFL spokesman said: “The EFL condemns the mindless actions of the individual who encroached on to the pitch at St Andrews on Sunday afternoon.
“It’s a situation no player should ever be faced with.
“In all circumstances the playing surface is for players, not supporters and 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.
