An argument between a couple led to a woman being hit in the head with a glass.
Michael Jones caused three cuts to his victim’s head.
The 26-year-old was given a suspended prison sentence when he appeared at Preston Crown Court.
Jones, of Kingsmede Avenue, Blackpool, pleaded guilty to a charge of assault occasioning actual bodily harm.
The offence happened on the evening of June 21 last year at an address on Hathaway Road, Fleetwood.
Nigel Beeston, prosecuting, said an argument started between the couple.
The defendant was holding a glass and his partner was trying to push him out of the house.
Somehow, the contents of the glass got spilled on her, the court was told.
The glass then left his hand and struck her on the head, causing the injuries.
She would later say that may have been accidental.
The police were called and Jones was arrested.
The woman’s injuries were treated with steri strips. She later made a retraction statement.
Chris Hudson, defending, said Jones had acted totally out of character.
“From the moment he did this folly, he has been very sorry for it. He has been genuinely frightened.
“It was an offence committed in drink. He had thrown the contents of a drink over her and the glass hit her too.
“He would sink like a stone if sent to prison.”
The judge accepted it had been a reckless, rather than an intentional act and arose on the spur-of-the-moment.
Jones was given eight months prison, suspended for 18 months, with 100 hours unpaid work.
He was told he must pay £500 compensation.
