The 35-year-old admits she's reconsidering her decision to retire as she sits on the precipice of the WNBL games record, but says she won't continue playing just to achieve a personal milestone.

Bibby made the startling revelation she has been playing with a hairline fracture near the "non-dangerous part of the spine" in her neck for the past three months following a collision with a teammate.

One more knock and Bibby will need surgery, but she's focused on the pursuit of a WNBL title.

"I'd be lying if I said I wasn't massively concerned when they said I had a fracture in my neck," Bibby said.

"I missed one game because of a sore neck in November. Then I had scans and there's a fracture on a previous fracture that I've had.

"But they told me it's not dangerous to play on, that's part of me weighing up whether I want to play next year. If I was to get another knock there's a chance I'd need surgery. I don't want that.

"I've got old-lady feet and now I've got an old-lady neck as well."

Bibby will line up for the Capitals in their must-win last-round clash against the Bendigo Spirit on Friday night, with a loss set to ruin the team's finals dreams and potentially end Bibby's career.

It will be her 370th WNBL match, moving her to fourth on the list of most games in the league's history.

She needs to play just another eight games to pass the record set by Rachael Sporn and Lucille Bailie, and she has one more season remaining on her contract with Canberra.

But after battling neck and feet problems this year and coming to terms with self-described "poor form", Bibby said in November she would retire at the end of the season.

The five-time WNBL championship winner desperately wants to go out on a high and missing the playoffs could convince her into one more season on the court.

But Bibby says she won't play just to reach the games record, insisting her focus is on being a contributor to the Capitals' championship bid.

"If you're playing for a record, that's not a reason to play. I love basketball and I will always have that passion for the sport," Bibby said.

"I don't want to be like John Farnham with the Last Time tour. I don't need to sugarcoat it, I've played poorly this year.

"If I still feel I can be a contributor then I will look at things. My body hasn't been great this year ... I don't want to be 36 years old and hold back a young kid if I'm not contributing. If we win the championship this season, that will be it."

Bibby's career has been an amazing tale of persistence and resilience. She broke her back 14 years ago after just 111 games and was told she would never play again, let alone walk.

She has put off any talk of retirement to focus on the finals. The Capitals need to beat Bendigo and rely on Sydney losing to Townsville to secure a playoff berth.

Bibby genuinely believes Canberra can be a championship threat.

"As far as I'm concerned, this isn't my last game. Hopefully we've got another month left, I don't want [talk of retirement] to be a distraction and I don't want it to be a ticking time bomb," Bibby said.

"I've been laughed at by doctors, I've seen the crazy looks on people's faces when I said I wanted to run around [after breaking my back].

"I remember making the WNBA and people laughed. I played for the [Australian Opals] when I was 30. I've been told, 'you can't, shouldn't, you're not going to, you're stupid' for as long as I can remember. Even my mum tells me to retire.

"But when you've got a passion that you love, you follow it. That's why I'm not looking at this game as the last."
