Round 1: This one should be interesting, as Dern came in seven pounds above the strawweight limit — and Cooper was rightfully pissed. The referee for this one is Osiris Maia. No touch of gloves, not surprisingly. Dern to the center, and they are sizing each other up. A left hand from Dern, and Cooper comes over top with a right. No mustard on that, and Dern rolls her shoulder and wheels around. A couple of left hands from Dern, and then she retreats and avoids the retaliation from Cooper. Awkward there for Dern. Dern with a big overhand right, and though it didn’t land flush it did land. Nice leg kick from Cooper, who is standing her ground. A big right from Dern, and that drops Cooper! Now Dern into mount, and immediately slamming Cooper with punches. Dern gets her back, and now her neck...it’s deep! And that’s it. Rear-naked choke. Damn. Dern dropped her with a punch first, then made short work of Cooper on the canvas.
