A trained boxer and cage fighter broke a woman’s cheek bone when he dived in to split up a fight between her and his ex-girlfriend.
Dominic Lee, 23, from Eversleigh Street, Preston, punched the woman twice in the face after she bit his finger when he tried to break up the brawl.
You should feel bitterly ashamed of yourself, whatever the provocation, for punching a woman. Men who punch women are generally known as cowards
Lee pleaded guilty to unlawful wounding after the fight spilled out into the garden at a party on October 10. He said he deeply regretted hurting her.
Victim Jenny Spencer was treated for her injury at Royal Preston Hospital.
Lucy Wright, prosecuting, said: “Miss Spencer had been drinking and when drunk she becomes hard work, loud and outspoken which can rub people up the wrong way.
“Lee attended the party and was handed a beer. Miss Spencer got upset and an argument started.
“Miss Spencer went for the defendant. He managed to hold her at arm’s length but she bit his thumb.
“She then pushed Lee’s partner Ashleigh with a clenched fist and they were fighting on the ground.”
Lee, who works as a plasterer and has a young daughter with his ex-partner, accepted he had lost his temper and punched Miss Spencer.
He told his defence lawyer David Farley he had taken “one step forwards and 200 steps back” after attempting to turn his life around from a previous record of violence.
Recorder Patrick Thompson, sentencing, said: “You yourself as a child witnessed domestic violence and in a way that aggravates your position.
“You should feel bitterly ashamed of yourself, whatever the provocation, for punching a woman. Men who punch women are generally known as cowards.
“You are very fortunate that you didn’t do much more damage than you did.
He handed Lee a nine-month sentence suspended for 18 months with supervision.
