UFC co-owner Lorenzo Fertitta made it official: UFC fighters will not be heading to Strikeforce on a regular basis.

Frank Mir, a former UFC heavyweight champion, is slated to meet Daniel Cormier in Strikeforce later this year. The bout will be the final one for Cormier in Strikeforce, fulfilling his contract obligations with Showtime, according to Fertitta.

“You’re not going to see more of it,” Fertitta said, in a recent interview with ESPN. “This is a one-time situation.”

Cormier won the Strikeforce Heavyweight Grand Prix by defeating Josh Barnett. Mir, meanwhile, is coming off a loss to UFC heavyweight champion Junior dos Santos.

Fertitta did make it known that Cormier, a former Olympic wrestler, will head to the UFC after the fight.
