A man has been given more than five years in jail after a single punch killed a father-of-two.
Thomas Allan, 52, assaulted Jason Haig, 45, at a pub in Rutherglen, South Lanarkshire, on September 2 last year.
The court heard how the pair had been playing pool together for about 20 minutes when there appeared to be a disagreement.
Allan approached Mr Haig during the game, spoke to him for a few seconds, and then struck him in the face with a single punch.
Mr Haig fell backwards and suffered a blow to his head as he hit the hard floor.
He was rushed to hospital with a fractured skull and a bleed on the brain.
The father-of-two died due to severe brain damage on September 10 at the Queen Elizabeth University Hospital, in Glasgow.
Allan, from Glasgow, pleaded guilty to culpable homicide at the High Court in Glasgow on December 17 last year.
He was sentenced at the High Court in Edinburgh on Monday to five years and four months behind bars, the Crown Office said.
David Green, procurator fiscal for homicide and major crime, said: "A single punch has had catastrophic consequences.
"This type of attack is just as lethal as an assault with a weapon and any instance of a punch to the head can have the kind of ramifications that we have tragically seen with this case.
"The unintended consequences of Thomas Allan's actions should serve as a stark warning that one punch can kill."
