Daniel Cormier will have 15 minutes inside the Octagon with former UFC heavyweight champion Frank Mir, and he plans to take advantage of each and every second.

The two will collide at UFC on FOX: Henderson vs. Melendez later this month. The bout was originally scheduled for last year in Strikeforce, but Mir suffered an injury.

It appears that the transition from Strikeforce to the UFC has provided Cormier with more of a trash-talking game, as he went off on Mir during a recent interview with Bleacher Report.

Mir has stated several times that he doesn’t believe “DC” has finishing power, and the former Olympian is firing back.

To the point of me not being a guy that can finish fights, I’m going to tell you right now and this is 100 percent true-Frank Mir says I can’t finish fights? Okay that’s fine. My intention in this fight is not to finish Frank Mir. I’m going beat up on Frank Mir for 15 minutes and I’m going to make him stay in that cage with me.If Frank Mir gets finished, it will be because he quit. We’ve all seen some of his fights where we’re like ‘what exactly happened there?’. Know that in this one, if he gets finished it will be because he quits. I’m going to make him check out of that fight, I’m not going to do it for him. I’m not going to do it for him. When he wants out of the fight, he’ll get out of the fight. So watch the fight on April 20. If Frank Mir gets finished it’s because he checked out.

Cormier is undefeated, including wins over Josh Barnett and Antonio Silva.
