A football fan has been jailed for 14 weeks after assaulting Aston Villa midfielder Jack Grealish on the pitch during the Championship match at Birmingham City.

Paul Mitchell, 27, had pleaded guilty at Birmingham Magistrates' Court on Monday.

He was also given a 10-year banning order from football matches. He has been banned for life at Birmingham City.

Meanwhile, Grealish, who earns £25,000 a week, was given £100 compensation "for the pain, discomfort and shock caused by the assault".

Passing sentence, magistrate Alison Fisher told Mitchell: "This type of behaviour is completely unacceptable - a view shared by your own football club.

"Mr Grealish has stated that he was shocked and scared and feels lucky that it wasn't worse. Players such as Mr Grealish are entitled to protection. We have therefore gone outside of our guidelines in the interests of justice."

During the court proceedings it emerged Mitchell's family had fled Birmingham due to the backlash faced, as his solicitor made an application to keep his address secret.

English midfielder Grealish, 23, was punched around the head by Mitchell around nine minutes into the derby as he stood in the Birmingham City penalty area.

Stewards intervened and Mitchell was led off the pitch.

Prosecutor Jonathan Purser told the court Grealish felt lasting pain after the incident but had suffered no substantial injury from a punch to the right side of his jaw.

In a statement read in court by Mr Purser, the Aston Villa captain said: "I cannot help but feel how lucky I was in this incident.

"It could have so much worse had the supporter had some sort of weapon."

Mitchell's solicitor Vaughn Whistance told the court: "He cannot explain what came over him yesterday morning. His initial foolish intention was to just go onto the pitch and whip up the crowd."

Birmingham City earlier said Mitchell would be banned for life from St Andrew's.

Making an application for the court to withhold Mitchell's home address, Mitchell's solicitor Mr Whistance told the court: "There have been various comments posted on different social media platforms.

"My client's young family have had to leave their home address to move to outside of Birmingham through fear that they would suffer serious harm or even death."

Magistrates have ordered a pre-sentence report on Mitchell and will pass sentence after 2pm on Monday.

The incident happened during Sunday's match between Aston Villa and Birmingham City, which Villa won 1-0.

Grealish scored the winning goal in the game.

The incident was one of a weekend marred by such altercations at football games.

Later on Sunday afternoon Manchester United defender Chris Smalling was also confronted on the pitch at Arsenal, while a supporter confronted Rangers player James Tavernier during their game against Hibernian at Easter Road on Friday.

Professional Footballers' Association chief executive Gordon Taylor said authorities must "put a lid on the problem" quickly and called on the Football Association to work with the government, police and stewards at the grounds to help stamp out such behaviour.

Minister for Sport Mims Davies called the incidents "a disgrace" and said: "It is right that they are investigated immediately and strong action is taken by the football authorities and clubs.

"Protecting players' safety is of paramount importance and every possible step must be taken to ensure that they are not put at risk."
