Two brothers who attacked a man outside a city centre bar have been jailed.
Leigh Storr and his brother Shane Middleton turned on William Elkington, 24, as he left the Walkabout Bar on Lincoln's High Street.
Robert Underwood, prosecuting, at Lincoln Crown Court said: "Mr Elkington saw a female outside the bar and believed her to be in distress.
"He walked over to attempt to speak to her. The next thing he was aware of was a blow to the head which knocked him senseless."
Mr Underwood said Mr Elkington was punched to the face by Middleton and then pursued as he tried to get away.
Middleton tripped Mr Elkington up and he was kicked by Storr when he fell over.
Mr Elkington was later taken to Lincoln County Hospital and treated for minor facial injuries.
Leigh Storr, 25, of Outer Circle Drive, Lincoln, and Shane Middleton, also known as Storr, 24, of Hemswell Avenue, Lincoln, each admitted assault occasioning actual bodily harm in the early hours of March 6.
Judge Michael Heath jailed each of them for 16 weeks.
He said: "Mercifully Mr Elkington only received minor facial injuries. You are very fortunate that the injury was not more serious."
Sam Skinner, for Leigh Storr, said the incident was out of character.
"On this occasion his brother had some extra money and so they decided to go into town. He drank more than usual and behaved in this disgraceful way," he said.
Sunil Khanna, for Shane Middleton, said he punched out because he believed Mr Elkington was "invading his space".
"He was shocked when his brother came in with a kick. This was one punch and a trip. It is not something that was planned."
