NSW veteran Craig Fitzgibbon says he will never retire himself from representative football but is treating Wednesday's Origin decider as his last game for the Blues.

While skipper Danny Buderus has confirmed the clash with Queensland at ANZ Stadium is his swansong, brought on by a move to England, Fitzgibbon refuses to put an end date on his time in the sky blue.

Recalled this year after two years in the Origin wilderness, the 31-year-old workaholic has been so buoyed by his rep comeback that he's pursuing another season with the Sydney Roosters next year.

"At this stage of my career I treat every rep game as it could be my last," said Fitzgibbon.

"I never thought I would be here. I have thoroughly enjoyed the series and whole camp atmosphere and I haven't been as proud as I was in game one when I put the blue jumper back on.

"I can't remember feeling that good in the sense of a personal achievement over the course of my career.

"I don't think I have got the right to retire from my rep career, I'm not that good a player.

"I just have to get in there and do my best until I don't get picked again."

Fitzgibbon has been one of NSW's better players over the opening Origin clashes, often leading the way with his high work rate and defensive intensity.

It has been the same work ethic he has carried throughout his stellar career.

Despite being a brilliant servant for the Blues - he has yet to lose an Origin series after being a pivotal figure in the 2003-05 hat-trick of titles - he says Wednesday should be all about Buderus and not what might be his own farewell.

"It's all about Bedsy," said Fitzgibbon.

"All the players mentioned during the week that we're all thankful to be playing in his last game."
