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, pleaded guilty at Birmingham Magistrates' Court on Monday.
He was also given a 10-year banning order from football matches.
Grealish, who earns £25,000 a week, was also given £100 compensation.
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.
