Bosses at Sky Television were not impressed.
"It was disappointing to see that language used in a tweet and it certainly is against Sky Television's policies to use language like that," head of corporate communications Kirsty Way said.
"Although I think Eric's followers may have seen the humour in it and many people may have seen the humour in it, especially when it's read in context with all of his tweets."
Ms Way said Young was still discussing the matter with his immediate boss and no discipline had been decided.
"We've spoken to Eric and expressed the fact that we're not happy with the tweet and we're pleased to see the apology," she said.
Ms Way said there had been no backlash from Prime viewers.
Last night's tweet, though it ruffled the feathers of some, was also defended as accurately reflecting the mood of New Zealanders that Adams had been robbed of her golden moment in London.
"Passionate and patriotic. We're with ya on this one," Susan McKone said.
"You're only saying what the rest of us are thinking," Nellie Lesa added.
Others were unforgiving, describing the language and attitude as "totally uncalled for" and "a bit rough".
"I can't imagine anyone will be letting him write his Prime News scripts anytime soon," the Throng NZ account tweeted.
The New Zealand Olympic Committee was contacted for comment but its representatives were on flights home.
In August last year Young caused a stir when he was caught giving rude finger gestures to the camera, which was broadcast on the Prime news bulletin.
