UFC 224 Results: Mackenzie Dern Submits Amanda Cooper in First Round

UFC 224 Live Stream

"Not shocked @MackenzieDern missed weight but 7.4lbs over is a disgrace to all professionals", Cooper tweeted.

If you haven't heard, Dern weighed in at 123 pounds for the strawweight fight, which is seven more pounds than the allowed limit. "I knew that Brazil would support me".

After the fight, Dern addressed missing weight by talking to the media who attended this latest pay-per-view event for the promotion.

As she's won't to do, Dern came out flinging heavy leather, much the way really good jiu-jitsu players do to make up for their lack of deep striking skills.

Despite the weigh-in slip-up by Dern, she and Cooper will still be part of a main card that will be main-evented by Amanda Nunes defending her bantamweight title against Raquel Pennington. Attempting to get out of harm's way, Cooper rolled but gave up her back to Dern who immediately locked in a rear-naked choke forcing Cooper to tap out. A lot of things have been happening. I don't want that to happen again but it's a mistake. "It's not an excuse, missed flights and a lot of things happened and I just kept going and going". I wasn't cutting anymore weight, I was in the sauna and there's no more water coming out, I wasn't sweating. Cooper started the fight aggressively, taking control of the center of the octagon and landed left hands.

It will be Dern's second fight in UFC. "The UFC is investing in me and I'm going to work with them not to happen ever again".

"I've always wanted to fight here in Brazil", she said. The UFC, since the first day I got here, were trying to help me and I said I was going to be able to make weight and I didn't.
