Teddy Roulston (30) of Ballycolman Estate in Strabane admitted inflicting grievous bodily harm on the man outside a Derry bar on June 11 last year.
The court was told that the injured party received 'very grave injuries' after the one punch assault resulted in him striking his head off the ground.
It was said that CCTV showed both men were drinking together in a bar and 'appeared friendly' they then an argument seemed to break out.
Roulston left the bar and the injured party followed.
Roulston then hit the injured party once and he fell to the ground with witnesses reporting there was 'a loud crack.'
A prosecuting barrister told the court that the injured party had 'very severe brain injuries'
A defence barrister said that his client 'deeply regretted' the consequences of his action.
He then read a personal letter from Roulston to the court. In the letter Roulston said: "I am so sorry for what I have put this man through.
Judge Philip Babington said his thoughts were with the injured party and his family and he adjourned sentencing to June 30.
