A Birmingham City fan has been jailed for 14 weeks for attacking Aston Villa captain Jack Grealish during the second city derby.
Paul Mitchell, of Rubery, Worcestershire, ran on to the pitch and hit Grealish from behind about 10 minutes into Sunday’s game.
Mitchell, 27, admitted assault and encroachment on to the pitch at Birmingham Magistrates’ Court earlier.
He “cannot explain what came over him yesterday morning”, his solicitor said.
“His initial foolish intention was to just go on to the pitch and whip up the crowd,” said Vaughn Whistance, defending.
Mitchell, of Cock Hill Lane, was also ordered to pay £350 in fines and costs and has been banned from attending any football matches in the UK for 10 years.
The £350 includes £100 in compensation for Grealish’s “pain, discomfort and shock”.
The Villa midfielder was able to continue with the game at St Andrew’s and went on to score the winning goal in the 67th minute.
Mitchell, a pub worker, claimed he was not drunk when he invaded the pitch and punched Grealish in the jaw.
“I cannot help but feel how lucky I was in this incident,” the player said.
“It could have been so much worse had the supporter had some sort of weapon.”
Birmingham City apologised to both Grealish and Villa immediately after the game and said Mitchell had been banned from St Andrew’s for life. He has also been banned from away games.
The club said there were “no excuses” for his behaviour, which “has no place in football”.
West Midlands Police said it was also investigating “offensive social media posts” that appeared after the goal referencing Grealish’s younger brother, who died when the midfielder was four.
Birmingham City said it had banned another supporter for life over the “vile and malicious” tweets.
Mitchell, who has been a season ticket holder for 20 years, was said to be “very remorseful” after realising he had “brought shame” on his club.
His defence asked for community service or a suspended prison sentence but magistrates ruled that a “message had to be sent out to fans”.
The father-of-one’s prison sentence “should be a deterrent”, magistrates added.
During the court hearing, Mr Whistance said online threats had been made to Mitchell.
Mr Whistance said his family had left the area “through fear that they would suffer serious harm or even death”.
An FA spokesperson said “a line had been crossed” and strongly condemned the attack, as well as another pitch invasion during the Manchester United and Arsenal match.
It has written to Birmingham City to examine the club’s security measures.
Former England player Phil Neville said drastic action was needed to ensure the safety of players.
“Either through points deductions or by emptying stadiums and making clubs play behind closed doors,” he said.
In 2002, a Birmingham City fan who ran on to the St Andrew’s pitch and confronted Aston Villa goalkeeper Peter Enckleman was jailed for four months for encroaching the playing area and using threatening behaviour.
