Roger's lawyer, James Elliott, said the argument broke out over a broken electronic toy or game and was a "storm in a teacup".
There had been some friction during the victim's stay at the house as Rogers believed his brother-in-law was abusing his hospitality, Mr Elliot said.
"Unfortunately it came to blows which never should have occurred."
His client had entered a guilty plea at the first opportunity, he said.
Addressing Rogers in sentencing, Judge Barbara Morris said he could only be described as having "lost it". "You hit him around the head a number of times so that he received a bleeding nose."
However, the assault was out of character for Rogers, who had not appeared before the court for 10 years, she said. Judge Morris sentenced Rogers to nine months supervision and ordered him to attend anger management and counselling.
