Amanda Cooper announced on social media that she is fighting Mackenzie Dern at UFC 224.

The bout has yet to be made official by the UFC. If signed and delivered, it would take place May 12 from Rio de Janerio, Brazil.

Dern made her Octagon debut recently, scoring a victory over Ashley Yoder. Cooper is a veteran of The Ultimate Fighter who has split her four UFC appearances.

“Fight Announcement!!! I can’t wait for this, in just eight weeks I’ll be in Rio fighting McKenzie Dern on UFC 224,” she wrote on Instagram. “I’ve been waiting for this fight longer then when I got the call for it, I’ve been waiting for this fight longer then when McKenzie got signed to UFC, I’ve been waiting for this for longer than when McKenzie get signed to Invicta, I’ve been waiting for this fight from the moment I heard her name.

“I’ve been training for this fight, I’ve been training for McKenzie and I’ve been training to beat her longer than you can imagine. I’m going to derail the hype train on May 12th.”
