A Scarborough youth suffered a broken nose after being head-butted by a man more than twice his age during a six-a-side football match in Scarborough.
The attack by 39-year-old Mark Andrew Jackson was said at York Crown Court to have “retaliated out of all proportion”.
The court heard Jackson had reacted after seeing the 17-year-old victim and another youth bullying a 14-year-old player.
The incident happened during a match between two teams called Liam’s and the Slick 6 on May 14, last year, during a six-a-side league game at Scarborough College’s sports hall.
Jackson, of Malton Road, in Staxton, who is also a committee member of the Westway Amateur Boxing Club, appeared before the court having previously admitted a charge of assault occasioning actual bodily harm.
Alan Mitcheson, prosecuting, told how the off-the-ball incident on the pitch was witnessed by the game’s referee who saw Jackson lunge at the youth and sent him off.
The victim also left the pitch in order to receive medical treatment.
The court heard a further incident the happened on the touchline involving the pair and the youth’s father, said Mr Mitcheson.
He added that, when quizzed by the police, Jackson told officers that he would resort to the same tactics again if he witnessed a repeat of what had happened on the pitch,.
Christine Mercer, mitigating, said that her client, who works for Plaxtons, was one of two adults playing alongside 14-year-old youths on the Slick 6 team.
She said Jackson had been acting in defence of his young teammate at the time of the incident.
She added, however, that it was accepted that matters had gone too far, and that Jackson agreed his actions had been excessive.
Miss Mercer said that Jackson, who has no previous convictions, was described in several references before the court in a very different light to how he had acted on this occasion.
Jackson was sentenced to a 12 month community order, with an eight week electronically monitored curfew between 8pm and 7am and a requirement to complete 180 hours unpaid work.
