Women's National Basketball Association (WNBA) All-Star Brittney Griner has filed a petition to annul her 28-day marriage to Glory Johnson, a forward with the Tulsa Shock.

The women, both 24, exchanged vows last month in Arizona, just weeks after police were called to the couple's home in Goodyear and both were arrested on allegations of assault and disorderly conduct. Griner subsequently pleaded guilty to disorderly conduct. She has agreed to undergo 26 weeks of counseling.

Both players were suspended seven games by the WNBA.

Griner, a Phoenix Mercury center, said in her annulment, filed June 5, that her marriage was “void based on fraud and duress,” adding that she was pressured to marry Johnson with “threatening statements.”

The filing came a day after Johnson announced that she was pregnant on Instagram.

Griner told ESPN that her wife's pregnancy came as a surprise and called the marriage a “huge mistake.”

“Sometimes you feel pressured into things. I went along with it,” she said.

Griner's annulment states that she has “no biological connection to petitioner and the unborn child.”

Greg Davis, a family-law lawyer in Scottsdale, Arizona, told The New York Times that under Arizona law there is a presumption that children conceived during a marriage belong to both spouses.

Johnson, who previously said that she is not a lesbian, told the AP that she was “not expecting to have our marriage end so abruptly.”

“I am ready to begin focusing on my health, pregnancy and am going to remain in Tulsa to continue to build my relationship with the Tulsa Shock organization, and my teammates,” she said in an email. “I appreciate the support of my fans, family and loved ones and look forward to returning to the basketball court as soon as I can.”
