Paul Mitchell, who punched Jack Grealish during Birmingham’s clash with Aston Villa yesterday, has been sentenced to 14 weeks in prison.
This morning, the 27-year-old pleaded guilty to assault to invading the pitch.
Mr Whistance Vaughan, defending, had said in mitigation: "He’s not a man you’d associate with any hooligan groups of football clubs.
"This was a highly-charged fixture and totally out of character. He has accepted his wrongdoing at the first opportunity.
"There’s already been consequences, threats made to his family over Facebook and other social media platforms and that’s his fault that has happened, by putting his family at risk due to foolish behaviour.
"Not surprisingly, this case has attracted a lot of national interest and I am mindful that a sentence will act as a deterrent today which would fall outside of the guidelines of common assault.
"No true football fans want to see this sort of behaviour and, thankfully, is very rare.
"This is a 27-year-old man who has come to the court before on a non-violent offence.
"This man will do as the court will tell him to. He’s a family man, they’re at the back at court. They are probably shocked and disgusted at his behaviour like those watching the unpleasant incident.
"His girlfriend is six weeks pregnant with their second child."
Earlier in the day, Jonathan Purser, prosecuting, had said: “Jack Grealish felt a push in the back and a hook to his lower jaw.
"He had just won a corner and had his back to the stand containing Birmingham City supporters.
“The TV footage had captured the defendant running onto the football pitch; Mr Grealish had his back to him, and had his name on the back of his shirt.
"Footage shows [Mitchell] taking a running swing, jumping on the back of Mr Grealish and launching that punch.
"The officer who was carrying Mitchell off the pitch said Mitchell thought Mr Grealish was 'a k**b'.
"Mitchell claims he was not intoxicated and was with his father and did it as a joke."
Birmingham have confirmed they have given Mitchell a lifetime ban from St. Andrew's.News Now - Sport News
