Butterworth, 26, who lost his arm in Iraq as a serviceman five years ago, was angry that athletics had received more lottery funding than cycling for the current Paralympic cycle - despite winning just two gold medals in Beijing, compared to cycling's 17.
He claimed the sport was having 'a laugh' and UK Sport officials should 'scrap all their funding, give it to cyclists and we’ll win double the medals we do already'.
However, the comments raised the ire of British team chef de mission Craig Hunter and athletics team leader Peter Erikkson and Butterworth was quick to say sorry.
“The team ethos is important to me and I apologise if I’ve upset any fellow athletes at the Games,” he said.
“I was ill-informed and wasn’t aware how hard the selection process is in athletics.
“This is my first Paralympics and I’m keen to do my talking on the track.”
