Mackenzie Dern has had a lot of hype behind, early on into her UFC run, but the strawweight prospect suffered a setback today in Rio de Janeiro, Brazil.

The decorated grappler came in at 123 pounds for her bout with Amanda Cooper, which is 7 pounds over the allowed limit. The fight is going ahead, however, Dern will forfeit 30% of her purse to Cooper.
