Strikeforce world female middleweight champion Cristiane “Cyborg” Santos (9-1 MMA, 3-0 SF) will be returning to the cage to defend her belt June 26, at the HP Pavilion in San Jose, CA. An opponent for the champion is yet to be announced.

Santos will be added to the already stacked “Strikeforce: Fedor vs Werdum” card. Also official on the card is the anticipated rematch between kickboxer Cung Le and the heavy handed Scott Smith. Headlining the night will be Fedor Emelianenko vs Fabricio Werdum.

“You’ll be able to come to San Jose or watch Showtime, and you’ll be seeing the No. 1 male and the No.1 female fighter in the world fighting on the same night,” said Strikeforce CEO Scott Coker.

“We’re still working on the details, but it will be somebody tough,” Coker said. “We’re looking at a couple of girls from Europe. We’re going to put somebody in there who will once again test her.”

A challenge is something Santos has not had since her first fight in May 2005, in which she lost to Erica Paes by kneebar. After her one and only loss she dominated nine straight wins over top female contenders. Of those nine wins, seven were impressive finishes by TKO .
