MMA Fighting’s Dave Meltzer is reporting that the cross-promotional heavyweight contest between Frank Mir and Daniel Cormier will take place November 3 from Oklahoma.

The bout will be the main event of a Showtime-televised card.

Mir, a former two-time UFC heavyweight champion, was recently defeated by Junior dos Santos in a title fight.

Cormier, an ex-Olympic wrestler, earned the Strikeforce Heavyweight Grand Prix crown by defeating Josh Barnett. He entered the GP as a replacement fighter.
