Jackson was originally thought to have added the milestone to her already brilliant career when she scored 18 points against Brazil in the Opals' 67-61 win.

But basketball's international body - FIBA - last night said there was an error.

''There was a duplicate of the Brazilian former player Janeth Arcain in FIBA's database,'' a statement read.

''Accordingly, Janeth Arcain's Olympic points total is 535, making her the current all-time women's Olympic scoring record holder.

''She leads Lauren Jackson, currently second with 497 points.''

Barring injury, Jackson will almost certainly break Arcain's record in London.

Last night's win was just what the Opals needed to get their gold-medal campaign back on track as they prepare to play against Russia tonight.

Jackson is spearheading the Opals' mission to break their silver-medal streak.

Australian women's basketball legend Michele Timms heaped praise on the Opals captain, who also carried the Australian flag into the opening ceremony last week.

''Absolutely she's the best. She's the greatest we've ever had without a doubt and internationally I think she's been one the greatest for the last seven years,'' Timms said.

''She works hard for every basket she gets, she gets a heck of a lot of attention and she's working overtime for them.

''It helps when she gets the help from Liz Cambage, who stepped up [against Brazil] as well.''

The Opals opened their Olympic campaign with a win against Great Britain, but they stumbled against France.

They were in cruise control for most of the match against Brazil before the deficit closed to just four points in the last minute.

Opals coach Carrie Graf hopes Jackson continues beyond London until at least the 2016 Olympics.

But after spending more than a decade at the top of international basketball, Jackson could call time on her Opals career in the coming years.

That's why the Opals are so desperate to send her out a winner.
