The undefeated Kaufman (10-0) informed FanHouse on Thursday that the organization told her that the highly anticipated 135-pound fight will happen on a yet-to-be announced show early next year.
Kaufman also said that she wasn't given a specific reason as to why the bout was postponed. She didn't suffer any kind of injury and she was unaware of Hashi being injured.
"I think it's a great fight," she said. "She's 12-1; she has a good record. She definitely knows how to win a fight, and I definitely think it would be a great fight."
MMA Junkie first reported that the bout was off the Nov. 20 show last week.
Strikeforce has yet to officially announce its plans to crown a 135-pound women's champion, but CEO Scott Coker has recently said that the organization will hold a tournament in the near future. And while many believed Kaufman vs. Hashi could qualify for a title fight, Kaufman said Strikeforce has yet to talk to her about that.
"I would love to have it for a title, but as of right now, I don't know [about] that."
The undefeated Kaufman is 2-0 in her Strikeforce career, already defeating Miesha Tate and Shayna Baszler earlier this year.
Hashi avenged the only loss on her resume in 2007 -- a 2005 submission to current Strikeforce fighter Hitomi Akano -- when she defeated Akano via unanimous decision in 2007. She also holds a notable victory over top contender Amanda Buckner.
