The first crossover match up between Strikeforce and the UFC finally has a date and venue set.

Former UFC heavyweight champion Frank Mir will clash with undefeated Strikeforce Heavyweight Grand Prix winner Daniel Cormier on Nov. 3 at the Chesapeake Energy Arena in Oklahoma City.  MMA Junkie first broke the news Sunday evening.

“DC” was an All-American wrestler at Oklahoma State University so this will be somewhat of a homecoming bout for him.

"I am excited to be going back to Oklahoma for this fight because it's been like my second home," Cormier, a Louisiana native, said. "My first fight was in Oklahoma, and the biggest fight of my Strikeforce career will be there," Cormier told MMA Junkie.

Mir, Brazilian Jiu-Jitsu black belt, respects Cormier’s talent, but still thinks he has the advantage in this fight.

"I'm excited to go to Strikeforce and challenge the best heavyweight there," Mir said. "Cormier is a top-10 fighter and is a great wrestler with a big right hand, but I can strike, too, and my Brazilian jiu-jitsu gives me the advantage if it does go to the ground,” he said.

"It's a very interesting fight and one I accepted right away when it was offered to me. The fight makes a lot of sense for me right now in my career."

Fans and analysts alike have been hoping for crossover fights between Strikeforce and the UFC when the UFC’s parent company, Zuffa, purchased Strikeforce in March of last year.

However, earlier this month, UFC CEO Lorenzo Fertitta told ESPN that this cross-promotional bout would be a “one-time” deal.

Cormier enters this fight on the strength of a one-sided decision win over another crafty submission specialist, Josh Barnett in May, while Mir was recently knocked out in the second round in a UFC 146 title fight with UFC heavyweight champion Junior dos Santos.
