4:31 PM PT -- In court docs obtained by TMZ Sports, Griner says she has NO biological connection to the baby ... and she doesn't know any of the key details about Johnson's pregnancy.
In short, it seems like Griner is suggesting they were not on the same page when it came to the pregnancy.
Griner also says the marriage to Johnson is based on "fraud and duress" -- because Griner was "pressured into marriage under duress by [Johnson's] threatening statements."
Griner does not specify the nature of the threats.
Griner also says there was fraud -- but does not say why. It seems to be related to the pregnancy.
As for the fetus, Griner does not say if she wants to have any type of parenting arrangement with the child. IT'S OVER -- WNBA superstar Brittney Griner has officially filed papers seeking to annul her 28 day marriage to her pregnant new wife Glory Johnson ... TMZ Sports has learned.
Griner and Johnson tied the knot on May 8th in a small ceremony in Arizona ... just weeks after they were both arrested in a domestic violence incident at their home.
The move is especially shocking considering Johnson just announced she's pregnant.
Johnson and Griner have been together for a while -- and even appeared on an episode of "Say Yes to the Dress: Atlanta" together back in January.
As we previously reported, Griner and Johnson were taken into custody for domestic violence on April 22nd. Both women say it was mutual combat after a heated argument got physical.
Griner later pled guilty to disorderly conduct and was ordered to complete a 26 week domestic violence counseling program. Johnson's case is still pending.
Both women were hit with 7 game suspensions from the WNBA ... though it's unclear how the league will handle the situation with Johnson, considering she's missing the entire 2015 season due to pregnancy.
