A man was left with a fractured eye socket after a mass brawl involving 60 people outside a Maltby pub, a court heard.
Sheffield Crown Court heard how Ricky Mangham joined in the punch-up outside The Sheppey on Grange Lane, Maltby, in order to stick up for his younger brother who was with him.
But he ended up felling Shaun Edwards with one punch, leaving him with swelling to the left of his face and a fractured eye rim.
Mangham, 25, admitted assault causing actual bodily harm when he appeared at Sheffield Crown Court for sentence.
Carl Fitch, prosecuting, said the 22-year-old victim had drunk about seven pints of beer with a friend before getting involved in the fight on the night in question.
He said there was a brawl involving up to 60 people outside the pub and Mr Edwards ended up in an argument with Mangham and his brother due to an apparent misunderstanding.
Mangham’s younger brother shouted at Mr Edwards and Mr Edwards felt a blow to the left side of his face and fell to the ground under the force of it.
In a statement read to the court Mr Edwards said: “It happened for no reason and was completely unprovoked.”
Robert Smith, defending, said Mangham, of Bentley Road, Bramley, told police he believed Mr Edwards had offered to fight his younger brother and was intervening in order to stick up for a family member.
He said he had just been to see his seriously ill father in hospital and was not in a good frame of mind, which led him both to excessive drinking and the subsequent involvement in the fight.
Mangham was given a 12-month community order, ordered to carry out 150 hours of unpaid work, and given a three-month curfew order by Recorder Margia Mostafa.
He was also ordered to pay Mr Edwards £500 compensation for the physical and psychological damage caused by the blow.
While handing out the sentence, Recorder Mostafa told Mangham: “You didn’t do your father or your family any favours by getting into this incident.”
