Ex-Strikeforce women’s featherweight champ Cristiane “Cyborg” Santos (10-1) is not fighting UFC women’s bantamweight champ Ronda Rousey (6-0 MMA, 0-0 UFC). Not yet, at least.

Santos on Wednesday told MMAjunkie.com (www.mmajunkie.com) that a notice on the UFC’s Portguese-language website announcing a fight between the women at UFC 157 is the “wrong information.”

She did, however, say that negotiations for the fight are underway, and said that she could fight at 135 pounds.

“In one month, I can’t do it, but if I have time, I could do it,” said Santos, who added that her management is currently negotiating with the UFC.

UFC 157 takes place Feb. 23 in Anaheim, Calif., which is Rousey’s Southern California home turf. The card does not yet have an announced main event, though a light heavyweight fight between Lyoto Machida and Dan Henderson has been targeted for the show.

Santos clarified that she could compete at UFC 157 at 145 pounds, but needed additional time to drop to the 135-pound limit needed to vie for Rousey’s title.

The conditions are a stark reversal for Santos, whose doctor recently said she would be unable to cut to 135 pounds without seriously affecting her health.

Word of the possible matchup quickly made Internet rounds. A UFC official said the posting was in error and the fight is not planned for UFC 157 or any upcoming card.

The two share a heated rivalry stoked by several interviews. Rousey has taken aim at Santos’ suspension for steroids, which came following a fight nearly a year ago against Hiroko Yamanaka and led to her being stripped of the featherweight belt. And Santos has repeatedly voiced her desire to silence the outspoken champ.

Santos’ suspension, a one-year term handed down by the California State Athletic Commission, which oversaw the bout, expires on Dec. 17.

Rousey most recently fought in August, when she defended her Strikeforce belt with a first-round submission of ex-champ Sarah Kaufman. UFC President Dana White recently said she would be the first woman to fight in the UFC and also would become the inaugural UFC women’s bantamweight champ. <
