Rumours that Petero Civoniceva may join Darren Lockyer in representative rugby league retirement are just that, according to the Queensland giant.

But if Civoniceva does change his mind ahead of what already looms as an emotion-charged State of Origin series decider next week, fellow Maroons prop Matt Scott reckons he will try to change his mind.

Speculation was rife on Tuesday that Civoniceva, 35, may be preparing for his Origin swansong ahead of next Wednesday night's Suncorp Stadium clash - much to his bemusement.

"It is the furtherest from my mind," he told AAP.

"I just want to focus on ensuring I can put in a performance I can be proud of and help Locky go out the way he deserves."

Civoniceva has nothing to prove on the representative front - he is the most capped Test forward (45).

And he has just overtaken good mate Steve Price's record for most Origins by a forward (28).

But as he eyed off Origin No.30, the Penrith powerhouse said he wouldn't be tempted to pull the plug on rep duty even if Queensland sent Lockyer out a winner with a sixth straight series win.

"Not really. I made a decision at the start of the year that I would make a call (on rep duty) at the end of the season," he said.

"Physically I am holding up really well.

"I am still loving being out there.

"I just want to see how I hold up leading the Panthers around at the back end of the season."

Then again, Scott admitted the modest Civoniceva was the sort of person who would keep his representative retirement under wraps in order not to steal Lockyer's thunder.

But if his fellow bookend did let it slip ahead of next week's decider, Scott said he would try to make him reconsider.

At 185cm and 105kg, Scott can be quite persuasive - but even he did not think he could make Civoniceva change his mind.

"I will try and talk him out of it but once he makes a decision I am sure it will be final," Scott told AAP.

"Hopefully itis not his last.

"It seems like he could go on forever big Pet.

"If it is he will keep it low key so he doesn't take the shine off Locky - that is the sort of bloke he is.

"He has been a massive influence - every time I play with him I learn something new.

"He would be missed but the platform that he and Steve Price laid, hopefully we can continue it on."

Queensland teammate Greg Inglis couldn't conceive Origin without Civoniceva.

"He is the godfather of Origin," he said.

"But we don't know what he is going to do.

"If he calls a meeting before kickoff, it would be a surprise for most of us but he knows that is best for him and we will respect any decision."
